Experiences of alien control in schizophrenia reflect a disorder in the central monitoring of action.

Twenty-three acute psychotic patients who were drug free at the time of testing performed a motor task designed to elicit many errors. Normal subjects and many of the psychotic patients were able to correct these errors in the absence of visual feedback. The ability to make such corrections depends on the subject knowing what response he has just made. Patients with experiences of alien control of their thoughts and actions who formed a subgroup of those classified as schizophrenic, were significantly less likely to make error corrections in the absence of visual feedback. This result is consistent with our previous suggestion (Frith, 1987) that these symptoms are a consequence of problems with the central monitoring of responses.

Cognitive therapy. A 30-year retrospective.

Several lines of investigation have evolved from the initial cognitive model of depression and other disorders. A large number of studies have tested the cognitive model using both clinical and laboratory-based strategies. In general, studies that most closely approximate the clinical conditions from which the theory was derived are supportive of the cognitive model of depression. Studies of anxiety and panic, although fewer, generally support the cognitive model of anxiety and panic. The application to the treatment of clinical problems has been promising and supports the concept of cognitive specificity. The cognitive therapy of depression has led to the utilization of specific cognitive strategies based on the specific conceptualizations of a given disorder to a wide variety of disorders. Study of abnormal reactions has also provided clues to the cognitive structure of normal reactions.

Young children's understanding of fact beliefs versus value beliefs.

Recent research on the development of children's knowledge about the mind has shown that young 3-year-olds have difficulty inferring that another person holds a false belief about a matter of verifiable fact, even when provided with considerable help. 4 studies tested the hypothesis that they would have less difficulty inferring that another person holds an odd, nonnormative belief about a matter of taste or value--one which, like the false fact belief, they themselves do not hold. On fact-belief tasks, an experimenter acted as if, or even explicitly stated that, she believed that the contents of a container were other than what the children knew to be the case. On value-belief tasks, she behaved as if she believed that a stimulus had a good or bad taste, smell, or appearance, whereas they thought it had the opposite. The results of all 4 studies confirmed the hypothesis.

Monitoring the source of memory in detoxified alcoholics.

The ability to monitor the source of remembered information and related reflective cognitive processes was examined in normal volunteers and detoxified alcoholics. Normal volunteers were very accurate judges of whether remembered events were presented as stimuli or were self-generated, even when memory was tested 2 days later. In contrast, a subgroup of otherwise cognitively unimpaired alcoholics demonstrated impairments in the ability to track the source of remembered knowledge and were also less able to inhibit intrusion errors in recalling information from memory. These findings provide preliminary evidence of an impairment in cognitive control functions in certain alcoholics. This conclusion is supported by associated findings indicating that, among alcoholics, performance on explicit memory tasks that required reflective cognitive operations were positively correlated with glucose utilization rates in left prefrontal, temporal, and posterior orbital frontal cortical regions.

Reasoning about the referent of a picture versus reasoning about the picture as the referent: an effect of visual realism.

Research on picture perception and picture-based problem solving has generally considered the information that enables one to "see" and think about a picture's subject matter. However, people often reason about a picture or representation as the referent itself. The question addressed here is whether pictorial features themselves help determine when one reasons about the referent of an image, as with an engrossing movie, and when one reasons about the image in its own right, as with abstract art. Two experiments tested the hypothesis that pictures with relatively high fidelity to their referents lead people to think about those referents, whereas pictures with relatively low fidelity lead people to think about the picture as a referent. Subjects determined whether marks on the bottom and top boards of an open hinge would meet if the hinge were closed. Accuracy and latency results indicated that subjects who saw realistic displays simulated the physical behavior of the hinge through analog imagery. In contrast, subjects who saw schematic displays tended to reason about static features of the display such as line lengths and angles. The results demonstrate that researchers must be cautious when generalizing from reasoning about diagrammatic materials to reasoning about the referents themselves.

The role of meta-cognitions and thought control techniques in predisposition to auditory and visual hallucinations.

OBJECTIVES: This study examines the relationship between a predisposition to hallucinations and meta-cognitive variables and thought-control techniques, controlling for the possible effect of anxiety. In order to do so, we start out with the hypothesis that anxiety does not, in itself, explain the association between meta-cognitions and a predisposition to auditory and visual hallucinations. DESIGN: A within-participants correlational design was employed. METHODS: Four psychometric tests relating to predisposition to hallucinations, anxiety, meta-cognitions and thought-control techniques were administered to 150 participants. RESULTS: It was found that, after controlling for participants' anxiety levels, the 'loss of cognitive confidence' factor predicted the score on the scale of predisposition to both auditory and visual hallucinations. Thought-control strategies based on worry were also found to be predictive of a greater predisposition to hallucinations, regardless of whether or not participants' anxiety level was controlled. CONCLUSIONS: Meta-cognitive variables of cognitive confidence and thought control through worry are positively associated with a predisposition to hallucinations. LIMITATIONS: The correlational nature of the design does not allow inferences about causal relationships.

False belief and sentence complement performance in children with specific language impairment.

BACKGROUND: Children with specific language impairment (SLI) have language abilities not commensurate with other cognitive abilities. This pattern makes the SLI population of interest when investigating the relationship between language and theory of mind. One view regarding this relationship is that theory of mind develops independently of language, but certain language skills are required to meet the demands of tasks used to measure theory of mind, such as false belief. Another view is that language development facilitates theory of mind development, and specifically, that mastery of sentence complement structures is necessary for false belief. AIMS: The study asked (1) if children with SLI can succeed on false belief, despite their language deficits, when the linguistic demands of the false belief task are low, and (2) if performance on sentence complement structures predicts false belief performance. METHODS & PROCEDURES: Fifteen children with SLI, 15 children matched for age and 15 children matched for language comprehension level participated in a false belief task with four conditions of differing linguistic complexity, and a test of sentence complementation understanding. Spontaneous production of sentence complements was also measured. Group differences for false belief and sentence complementation, and condition differences for false belief, were tested non-parametrically. Partial correlation analysis, log-linear analysis, and Wilcoxon-Mann-Whitney tests were used to explore relationships among the complementation and false belief measures for all children and for each group. OUTCOMES & RESULTS: Children with SLI performed similarly to age-matched peers on false belief when linguistic complexity of the task was low, and performed more poorly than age-matched peers on understanding of sentence complements. For all children, sentence complement performance was correlated with false belief (controlling for age), and those who performed well on sentence complements had higher mean rates of false belief success. Log-linear analysis showed the sentence complement-false belief relationship to hold for a condition with relatively low linguistic demands. CONCLUSIONS: The study provides evidence that children with SLI can perform at age-appropriate levels when false belief tasks are less demanding, and that mastery of sentence complementation is a predictor of false belief ability.

Visual search in simple simulations of realistic scenes.

The effect distracting objects have on visual-search performance in real-life situations cannot readily be predicted from current search theories. The validity of an approach to close this gap was tested by comparing search performance for color slides of scenes in public buildings with performance for simplified computer-generated images derived from these slides. The target was always a blue rectangle in both the original slides of scenes and the computer simulations. The distractors were differently colored rectangles (not blue), and their number was varied systematically. Analysis showed a significant linear increase in search time with number of distractors, which challenges predictions of current search theories. An explanation for this contradiction is proposed. Also, search times for color slides were significantly longer than those for computer images; however, there was no significant interaction between type of stimulus and number of distractors. It is concluded that the simulated scenes yielded adequate predictions of the effect of distracting objects on search performance in real-life situations.

Theory of mind and rule use in individuals with Down's syndrome: a test of the uniqueness and specificity claims.

The relationship between Theory of Mind (ToM) and rule use was explored in adults with Down's Syndrome (DS) and in non-handicapped pre-schoolers. Twelve low-functioning individuals with DS (mean mental age = 5.1 years, mean chronological age = 22.7) performed worse than 12 MA-matched non-handicapped children (mean MA = 5.1 years) on several standard ToM tasks and on a color-shape card-sorting task in which subjects were required to switch between two incompatible sets of rules. On the ToM tasks, people with DS tended to focus on a single state of affairs (e.g. the present situation). Likewise, on the card sort, these subjects tended to use a single set of rules on all trials. Performance in the two types of task was positively correlated when MA was partialed out. The results are inconsistent with the slaim that ToM reflects a domain-specific psychological function and the notion that deficits in ToM are unique to individuals with autism.

An inkblot for attitudes: affect misattribution as implicit measurement.

Misattributions people make about their own affective reactions can be used to measure attitudes implicitly. Combining the logic of projective tests with advances in priming research, the affect misattribution procedure (AMP) was sensitive to normatively favorable and unfavorable evaluations (Experiments 1-4), and the misattribution effect was strong at both fast and slow presentation rates (Experiments 3 and 4). Providing further evidence of validity, the AMP was strongly related to individual differences in self-reported political attitudes and voting intentions (Experiment 5). In the socially sensitive domain of racial attitudes, the AMP showed in-group bias for Black and White participants. AMP performance correlated with explicit racial attitudes, a relationship that was moderated by motivations to control prejudice (Experiment 6). Across studies, the task was unaffected by direct warnings to avoid bias. Advantages of the AMP include large effect sizes, high reliability, ease of use, and resistance to correction attempts.

Can autistic children distinguish lies from jokes? A second look at second-order belief attribution.

Previous studies show that autistic children fail tests of second-order belief attribution. They also fail tests of lying and deception. The present study used Leekam's (1988) joke-lie distinction task to test (a) understanding of second-order mental states (intention and belief) and (b) the ability to judge these acts as lies or jokes. Seventeen normal and 16 autistic children took part. Eight of the autistic children had previously passed a test of first-order false belief. Results showed that six autistic subjects (37.5%), all of whom are false belief "passers", gave consistently correct answers to second-order mental state questions. Neither normal nor autistic children found second-order intention easier than second-order belief. However, normal children found the ability to judge another person's mental state easier than labelling whether the person was lying or joking, supporting previous evidence. In contrast, there was no difference in these two judgements for autistic children. Overall these results qualify previous evidence by showing that autistic children can use second-order reasoning and can distinguish lies from jokes. Observational data on these children, however, suggest that their competence on the comprehension of these hypothetical situations was not matched by an ability to use lying and joking in real life. Methodological, language and diagnostic factors are discussed as providing possible explanations for the results.

Recognizing the un-real McCoy: priming and the modularity of face recognition.

Fodor (1983) has proposed that face perception is carried out by an informationally encapsulated module, whose operation is unaffected by context or expectancies. We tested the modularity hypothesis by examining whether discriminations between normal and distorted versions of famous faces can be primed, either by the name of an associated person (semantic context) or by a valid cue as to the identity of the target face (expectancy). A preliminary experiment showed that, in the absence of priming, discriminations between normal and distorted versions of a face were unaffected by whether the target faces were familiar or not, confirming that these judgments tap perceptual, not postperceptual (semantic), coding processes. In Experiment 1, accuracy was significantly higher when target face pairs were preceded by related name primes, as compared with unrelated ones. In Experiment 2, reaction times were significantly faster for targets preceded by a valid identity cue than for targets preceded by an invalid one. Neither effect could be explained as a speed-accuracy tradeoff. These results fail to support Fodor's conjecture that face processing is encapsulated.

Age trends in the use of social and temporal comparison for self-evaluation: examination of a novel developmental hypothesis.

Two studies tested the novel hypothesis that children use social comparison (SC) for self-appraisal at an earlier age than they do temporal comparison (TC). The effect of other's and of own prior outcome on performance and ability appraisal and on self-evaluative strategies was examined using simple tasks and outcome information. Results from 840 children at ages 4-8 confirmed that self-evaluative SC was similar over age. Even 4- to 5-year-olds rated themselves higher after doing better versus worse than another and explained their ratings in terms of explicit SC. Social failure undermined continuing motivation at all ages. In contrast, young children in TC conditions attended only to their last outcome, and comparisons between current and prior outcomes increased with age. Self-evaluative biases were marked at age 5-6 and for boys in SC conditions. Results clarify the role of cognitive and motivational factors in the development of SC and TC.

Intention and knowledge in preschoolers' conception of pretend.

Experiments 1 and 2 investigated 3- and 4-year-olds' understanding of the intended nature of pretend behaviors by testing their ability to distinguish between involuntary behaviors and the same behaviors emitted intentionally through acts of pretend. Four-year-olds' high rate of passing showed that (1) they understood intention as a mental cause of action and (2) they construed pretend behaviors mentalistically. Experiment 3 used the same contrastive procedure to examine Lillard's contention that 4-year-olds do not understand the knowledge conditions and hence the mental representational component of pretend actions. Whereas nearly all of the 5-year-olds understood that an agent who did not know of a specific animal could not be pretending to be that animal, 4-year-olds systematically associated ignorance with pretend. On the basis of the combined findings of the present experiments, and other research showing a mentalistic understanding of pretense by the age of 3 or 4, it was concluded that the specific reasoning requirements of Lillard's tasks resulted in an underestimation of children's appreciation of the mental features of pretend.

Maintenance of grip on life and goals of life: a valuable criterion for evaluating outcome in schizophrenia.

This article describes the evaluation of schizophrenia patients' maintenance of grip as a comprehensive assessment of the total psychosocial status of these patients. This evaluation was tested with new schizophrenic patients (DSM-III) who took part in a standardized interview at entry and after a 2-year follow-up. The interviews and examinations were conducted by the psychiatric teams responsible for the treatment of the patients. There was a clear positive correlation between the evaluation of maintenance of grip and interpersonal interaction, heterosexual development, hobbies, level of activity and productivity (working) of the patients, and a negative correlation with negative symptoms. The psychodynamically interpreted evaluation of the degree of regression correlated positively with maintenance of grip, but only after the 2-year follow-up. At entry the other variables describing the psychosocial status of the patient explained 22% of the variation in maintenance of grip, but 41% at the follow-up stage. The evaluation of maintenance of grip presented at baseline also predicted the coping of the patients during the follow-up stage. The authors recommend that the evaluation of maintenance of grip be used as an auxiliary tool in the assessment and treatment of schizophrenia patients.

Perceptual interaction between real and synesthetic colors.

People with color-graphemic synesthesia experience vivid, reliable color upon viewing achromatic alphanumeric characters. Recent evidence indicates that synesthetic color experiences are as perceptually real as actual colors are for non-synesthetic observers. To investigate possible interactions between real and synesthetic colors, we tested two adult color-graphemic synesthetes on a pair of perceptual grouping tasks. In Experiment 1, we employed a well-known phenomenon of motion perception, bistable apparent motion, to explore whether synesthetic colors interact with real colors in grouping over time. Two-frame apparent motion sequences were presented with both path lengths and colors systematically manipulated. Results showed that synesthetic colors of motion tokens interacted with matching real colors of the corresponding motion tokens, which could subsequently bias perceived direction of motion. In Experiment 2, we exploited binocular rivalry, a condition under which two dissimilar monocular images compete with each other and result in perceptual switches, to explore whether synesthetic colors interact with real colors in grouping over space. Pairs of rival images with two different characters were presented dichoptically with colors of characters manipulated. Results showed that synesthetic and real colors of characters tended to group together, which, in turn, promoted the perceived global dominance during binocular rivalry. Therefore, the present results identify substantial interaction between synesthetic colors and real colors in perceptual grouping.

[Specificity hypothesis of a theory of mind deficit in early childhood autism].

OBJECTIVES: In order to test the hypothesis that a theory of mind deficit is specific for autism, the present study presents the first replication of the Sally-Anne test (Baron-Cohen, Leslie & Frith, 1985) in the German-speaking countries. METHODS: The Sally-Anne test was administered to 16 autistic, 24 probands with Down's syndrome and 20 normal preschool prosands. The intelligence of the autistic group and that with Down's syndrome was measured by the CPM/SPM. In addition, the ADI-R was used with the principal caregivers of the autistic and Down's syndrome subjects. RESULTS: With regard to the clinical diagnosis, theory of mind deficit turned out to be not specific for autism. Six of 16 (37.5%) autistic subjects passed the theory of mind tasks. Thus performance in the autistic group surpassed that of both control groups. Out of 16 autistic subjects, autism could be confirmed in only 8 on the basis of the ADI-R diagnostic criteria, only one of whom showed a theory of mind. The autistic individuals with a theory of mind differed significantly in their mean IQ from those without this ability. CONCLUSIONS: Spectrum and specificity of a theory of mind deficit in autism remain controversial. For further research it seems important to administer the ADI-R during the diagnostic process. The findings suggest that the clinical diagnosis of autism is not precise enough to distinguish between autism and nonautistic mental handicap.

2.5-month-old infants' reasoning about when objects should and should not be occluded.

The present research examined 2.5-month-old infants' reasoning about occlusion events. Three experiments investigated infants' ability to predict whether an object should remain continuously hidden or become temporarily visible when passing behind an occluder with an opening in its midsection. In Experiment 1, the infants were habituated to a short toy mouse that moved back and forth behind a screen. Next, the infants saw two test events that were identical to the habituation event except that a portion of the screen's midsection was removed to create a large window. In one event (high-window event), the window extended from the screen's upper edge; the mouse was shorter than the bottom of the window and thus did not become visible when passing behind the screen. In the other event (low-window event), the window extended from the screen's lower edge; although the mouse was shorter than the top of the window and hence should have become fully visible when passing behind the screen, it never appeared in the window. The infants tended to look equally at the high- and low-window events, suggesting that they were not surprised when the mouse failed to appear in the low window. However, positive results were obtained in Experiment 2 when the low-window event was modified: a portion of the screen above the window was removed so that the left and right sections of the screen were no longer connected (two-screens event). The infants looked reliably longer at the two-screens than at the high-window event. Together, the results of Experiments 1 and 2 suggested that, at 2.5 months of age, infants possess only very limited expectations about when objects should and should not be occluded. Specifically, infants expect objects (1) to become visible when passing between occluders and (2) to remain hidden when passing behind occluders, irrespective of whether these have openings extending from their upper or lower edges. Experiment 3 provided support for this interpretation. The implications of these findings for models of the origins and development of infants' knowledge about occlusion events are discussed.
