Affect as information in persuasion: a model of affect identification and discounting.

Three studies examined the implications of a model of affect as information in persuasion. According to this model, extraneous affect may have an influence when message recipients exert moderate amounts of thought, because they identify their affective reactions as potential criteria but fail to discount them as irrelevant. However, message recipients may not use affect as information when they deem affect irrelevant or when they do not identify their affective reactions at all. Consistent with this curvilinear prediction, recipients of a message that either favored or opposed comprehensive exams used affect as a basis for attitudes in situations that elicited moderate thought. Affect, however, had no influence on attitudes in conditions that elicited either large or small amounts of thought.

Likelihood-ratio affected sib-pair tests applied to multiply affected sibships: issues of power and type I error rate.

"All-pairs" likelihood-ratio analyses, such as those performed by MAPMAKER/SIBS [Kruglyak and Lander, 1995], require that a sibship containing N affected siblings be split into N(N - 1)/2 sibships, each containing a different pair of affected sibs, before analysis. Each of these N(N - 1)/2 sibships may also contain the other affected sibs from the original sibship, coded as unaffected, to infer missing parental genotypes, as is done automatically in MAPMAKER/SIBS. Then, the use of the same individuals both as affecteds to test for linkage and, elsewhere, as unaffecteds to infer missing parental genotypes leads to negative correlations in the estimated identity by descent sharing among affected pairs from the same original multiplex sibship. This gives a conservative test of linkage, even when no downweighting is applied. Conversely, if the other affected sibs from the original sibship are omitted, the correlations are positive and the linkage test is anticonservative in the absence of weighting. True type I error probability also depends on marker informativity, typed parents, number of affected sibs included in the analysis, and the weighting scheme. This suggests the use of simulation, rather than asymptotic theory, to assess significance levels. The power of multiplex sibships relative to affected pairs increases with increasing phenocopy percentage, but the presence of typed unaffected sibs improves the relative power of multiplex sibships greatly only when penetrance is high. It was found that the 2/N weighting proposed by Suarez and Hodge [1979] increased power over an unweighted analysis in many situations, provided significance levels were adjusted appropriately by simulation.

Prevalence of swine Torque teno virus in post-weaning multisystemic wasting syndrome (PMWS)-affected and non-PMWS-affected pigs in Spain.

The present study was designed to investigate the prevalence of swine Torque teno virus (TTV) in post-weaning multisystemic wasting syndrome (PMWS)-affected and non-affected Spanish swine. Nested PCR (nPCR) assays to detect two distinct TTV genogroups were applied. A significantly higher prevalence of TTV infection was found in sera from PMWS-affected animals (97 %) than in sera from non-PMWS-affected animals (78 %). Whilst PMWS-affected pigs (91 %) were more likely to be infected with TTV from genogroup 2 than non-PMWS-affected swine (72 %), no such difference was observed with genogroup 1. Nucleotide sequences of nPCR products were 91-99 % identical between strains within a genogroup. In contrast, inter-genogroup sequence identities were 49-58 %. Phylogenetic analyses demonstrated that genogroups form different clusters without association with PMWS or porcine circovirus type 2 infection status of the animals. These results indicate a high prevalence of both swine TTV genogroups in Spain, being present more frequently in PMWS-affected animals than in non-PMWS-affected animals.

Children's affective responses, cognitive appraisals, and coping strategies in response to the negative affect of parents and peers.

Although research has linked difficulties in parent mood functioning to developmental problems in children, little work has examined why such a link occurs. Following current social-cognitive perspectives on children's cognitive appraisals to negative parent affect, it was hypothesized that children would show more intense affective responses, less confidence, and less active coping strategies in response to parent, as opposed to peer, negative affect. In the current study, young children (N = 39) were read experimental vignettes portraying peers and parents in either happy, sad, or angry emotional states. Children were then interviewed about their affective responses, cognitive appraisals, and coping strategies to each vignette. Beyond experiencing more negative affective responses to parent, compared to peer negative affect, children felt they could do little to help themselves when faced with paternal distress and frequently indicated they would engage in avoidant coping strategies (e.g., hiding) to make themselves feel better when confronted with parent sadness. This study has implications for more industrious future research, as well as intervention projects that involve assisting children who live in households marked by high levels of negative adult affect.

In the mood for love or vice versa? Exploring the relations among sexual activity, physical affection, affect, and stress in the daily lives of mid-aged women.

How do physical affection, sexual activity, mood, and stress influence one another in the daily lives of mid-aged women? Fifty-eight women (M age, 47.6 yrs) recorded physical affection, several different sexual behaviors, stressful events, and mood ratings every morning for 36 weeks. Using multilevel modeling, we determined that physical affection or sexual behavior with a partner on one day significantly predicted lower negative mood and stress and higher positive mood on the following day. The relation did not hold for orgasm without a partner. Additionally, positive mood on one day predicted more physical affection and sexual activity with a partner, but fewer solo orgasms the following day. Negative mood was mostly unrelated to next-day sexual activity or physical affection. Sexual orientation, living with a partner, and duration of relationship moderated some of these effects. Results support a bidirectional causal model in which dyadic sexual interaction and physical affection improve mood and reduce stress, with improved mood and reduced stress in turn increasing the likelihood of future sex and physical affection.

Does affective blunting in schizophrenia reflect affective deficit or neuromotor dysfunction?

Schizophrenia inpatients withdrawn from all neuroleptic medication were administered measures of affective blunting, diminished affective experience, and neuromotor dysfunction. The correlations among the measures provided support for the hypothesis that measures of affective blunting reflect both neuromotor and affective deficits. Because the interpretation of such measures is therefore ambiguous, measures of diminished affective experience may have greater validity in research on affective deficits in schizophrenia than measures of blunted affective expression.

Affect, cognition, and awareness: affective priming with optimal and suboptimal stimulus exposures.

The affective primacy hypothesis (R. B. Zajonc, 1980) asserts that positive and negative affective reactions can be evoked with minimal stimulus input and virtually no cognitive processing. The present work tested this hypothesis by comparing the effects of affective and cognitive priming under extremely brief (suboptimal) and longer (optimal) exposure durations. At suboptimal exposures only affective primes produced significant shifts in Ss' judgments of novel stimuli. These results suggest that when affect is elicited outside of conscious awareness, it is diffuse and nonspecific, and its origin and address are not accessible. Having minimal cognitive participation, such gross and nonspecific affective reactions can therefore be diffused or displaced onto unrelated stimuli. At optimal exposures this pattern of results was reversed such that only cognitive primes produced significant shifts in judgments. Together, these results support the affective primacy hypothesis.

Affect networks: a structural analysis of the relationship between work ties and job-related affect.

The relationship between organizational networks and employees' affect was examined in 2 organizations. In Study 1, social network analysis of work ties and job-related affect for 259 employees showed that affect converged within work interaction groups. Similarity of affect between employees depended on the presence of work ties and structural equivalence. Affect was also related to the size and density of employees' work networks. Study 2 used a 10-week diary study of 31 employees to examine a merger of 2 organizational divisions and found that negative changes in employees' affect were related to having fewer cross-divisional ties and to experiencing greater reductions in network density. The findings suggest that affect permeates through and is shaped by organizational networks.

Individual difference variables, affective differentiation, and the structures of affect.

Methodological arguments are usually invoked to explain variations in the structure of affect. Using self-rated affect from Italian samples (N=600), we show that individual difference variables related to affective differentiation can moderate the observed structure. Indices of circumplexity and congruence coefficients to the hypothesized target were used to quantify the observed structures. Results did not support the circumplex model as a universal structure. A circular structure with axes of activation and valence was approximated only among more affectively differentiated groups: students and respondents with high scores on Openness to Feelings and measures of negative emotionality. A different structure, with unipolar Positive Affect and Negative Affect factors, was observed among adults and respondents with low Openness to Feelings and negative emotionality. The observed structure of affect will depend in part on the nature of the sample studied.

Ego function assessment of schizo-affective patients as compared to schizophrenic and affective psychotic patients.

A 1-year sample of consecutively admitted patients between 18 and 40 years of age is studied. Psychopathology has been elicited by the Schedule for Affective Disorders and Schizophrenia (SADS), and diagnoses have been set according to Research Diagnostic Criteria (RDC). The sample consists of 57 cases with schizophrenia, 8 cases with schizo-affective psychosis and 23 cases with affective psychoses. Bellak's Ego Function Assessment Test was given to all these patients. The test does not show any significant differences between the schizo-affective and the schizophrenic groups. Some significant differences are found between the schizo-affective group and the group of affective psychosis. The findings do not validate schizo-affective psychosis as a diagnostic category.

Affect in psychoanalytic theory: discussion of André Green's 'on discriminating and not discriminating between affect and representation'.

André Green's 1999 programmatic essay on affect and representation, an attempt to extend Freud's model of the neuroses (where affect and representation have different vicissitudes) to non-neurotic cases is submitted to critical reading. Green wishes to restore the importance of representation; to use the second topographical theory, where id, psychical impulse and object-cathexis replace the unconscious and the ideational representation in order to conceptualize borderline disturbance, and to show how ultimately the 'non-discrimination' affect-representation obtains in non-neurotic cases as well. The author, interested in the question posed in Green's essay as to what we have to sell our borderline patients, addresses the various reasons why this project fails. Among the problematic points are the paradox of Green's model of unconscious affect, that does not allow the analyst to generate meaning with borderline patients, the view of 'representation' as replacing presence and perception of the object that does not allow the analyst to be a non-absent object, and the inability to conceptualize affect-representatives and to work out the definition of affect as 'the anticipation of a meeting with the other's body' which does not allow the analyst to function as an 'anticipatory object' or 'an object of affect'.

On a disturbance of affectivity in schizophrenic adolescents: implications for affect theory.

As recently as 1969 Loeb stated, "Not only has adolescent schizophrenia been largely ignored by the clinician and research worker but until recent years the entire subject of adolescence had received scant attention" (p. 462). Since that time, a number of investigators have attended to similarities and differences between the schizophrenic syndrome, as a whole, and schizophrenia as it appears in adolescence. One of the findings that has been alluded to by some authors concerns the notion that affect is less severely disturbed, especially in the dimension of affective responsiveness, in adolescent schizophrenics (Sands, 1956). Observations by the author and others suggest that greater attention be paid to the variety of affectivity to delineate this area of symptomatology, which both Kraepelin and Bleuler considered so fundamental and typical in their designations of dementia praecox and schizophrenia. Indeed the purpose of this study concerns the description and dynamic understanding of a typical disturbance of affectivity in adolescent schizophrenics. This disturbance is characterized by a quality of affective communication in which the patient relates to the people around him in a superficial, socially acceptable, receptionist-like manner which induces in the observer the impression that the individual's genuine feelings are not prominent. For want of a better term, we may designate this affective state "airline-hostess affectivity" (A.H.A.). The disturbance is not exclusive to adolescent schizophrenics but can also be observed in young adults too before a phase of chronic adaptation to the schizophrenic process.

Examining the association between rumination, negative affectivity, and negative affect induced by a paced auditory serial addition task.

The present study examined the relations among a depressive ruminative response style, a general propensity to experience negative affectivity, and negative affect induced by a paced serial auditory addition task (PASAT). Ninety nonclinical individuals completed a computerized version of the PASAT, which elicits a generalized negative affect response [Lejuez, C. W., Kahler, C. W., & Brown, R. A. (2003). A modified computer version of the paced auditory serial addition task (PASAT) as a laboratory-based stressor: Implications for behavioral assessment. Behavior Therapist, 26, 290-292]. As hypothesized, there was a moderate correlation between depressive rumination and a propensity to experience negative affect, as indexed both by a significant association with a negative affect personality factor and the prediction of negative affect elicited during the provocation. Findings also suggested that dispositional negative affectivity moderated the effects of a depressive ruminative response style on the valence but not arousal dimensions of emotional responding to the challenge. These findings are discussed in terms of improving our understanding of rumination and its potential role in emotional vulnerability processes.

Individuals with the dominant hand affected following stroke demonstrate less impairment than those with the nondominant hand affected.

OBJECTIVE: The purpose was to determine if upper extremity impairment and function in individuals with chronic stroke is dependent upon whether the dominant or non-dominant hand is affected. METHODS: Ninety-three community-dwelling individuals with stroke. The Modified Ashworth Scale (tone), handheld dynamometry (isometric strength), monofilaments (sensation), Brief Pain Inventory (pain), Chedoke Arm and Hand Activity Inventory Motor Activity Log (paretic arm use), and Reintegration to Normal Living Index (participation) were used to form impairment and function models. RESULTS: Multivariate analysis models (Dominance x Severity) were created for impairment and function variables. There was a significant interaction and main effect of Dominance for the impairment model (P = 0.01) but not the function model (P = 0.75). The dependent variables of tone, grip strength, and pain were all significantly affected by Dominance, indicating less impairment if the dominant hand was affected. All dependent variables except pain were affected by Severity. CONCLUSION: This study looked at the effect of the dominant hand being affected versus the nondominant in individuals with chronic stroke. Individuals with the dominant hand affected demonstrated less impairment than those with the nondominant hand affected. However, there was no effect of dominance on paretic arm use or performance in activities of daily living. Prospective studies to further explore the issue of hand dominance and poststroke function are suggested.

Transient sensory, cognitive and affective phenomena in affective illness. A comparison with complex partial epilepsy.

Behavioural changes have often been noted in patients with epilepsy. This study investigated the converse phenomenon--the occurrence of transient sensory, cognitive and affective changes resembling those described by epileptics, in affectively ill patients. Forty-four patients with affective illness, 37 with complex partial seizures, and 30 hypertensive controls were interviewed to determine the lifetime occurrence of these phenomena. Such symptoms occurred frequently in association with episodes of affective illness and epilepsy, but were rare in controls. Visual, auditory, olfactory and epigastric symptoms, illusions, jumbled thoughts and amnesia were common to both epilepsy and affective illness. Greater numbers of symptoms were associated with better response to lithium and tricyclic antidepressants. Transient sensory, cognitive, and affective phenomena may be more common in affective illness and other psychiatric conditions than is generally recognised, and may be clues to the underlying pathophysiology of these conditions.

The role of negative affect and positive affect in stress, depression, self-esteem, assertiveness, Type A behaviors, psychological health, and physical health.

Dua (1989) constructed the Thoughts and Real-Life Experiences Scale (THARL) to assess the degree of positive and negative affect experienced by people as a result of their thoughts and day-to-day experiences. This monograph reports on a number of studies designed to investigate the relationship between negative and positive affect caused by thoughts and day-to-day experiences and psychological health, psychological problems, and physical health. Results showed that a preponderance of self-reported negative affect was related to higher levels of stress, depression, poor psychological well-being, poor psychological health, lower self-esteem and poor self-reported retrospective physical health. A preponderance of negative affect was associated with only one of the two measures of prospective physical health, namely, the number of visits to doctors for medical problems over a period of 4 weeks. Positive affect was not associated with either self-esteem or physical health. Assertiveness and Type A/B behaviors were not associated with either negative or positive affect. Also, of the two measures of negative affect, that caused by thoughts seemed to be a better predictor of health, well-being, and psychological problems than that caused by day-to-day experiences.

Development of a measure that integrates positive and negative affect and personality: the Comprehensive Personality and Affect Scales.

The development, reliability and validity of a new measure of personality and affect, the Comprehensive Personality and Affect Scales (COPAS) was investigated in three studies of college students. In study 1, the factor structure of personality, negative affect, and positive affect was assessed, with five-factors found in each of the three analyses. Fifteen scales (Personality: Emotionality, Extroversion, Openness, Conscientiousness, and Agreeableness; Negative Affect: Depression, Hostility, Agitation, Anxiety, and Social Anxiety; Positive Affect: Contentment, Joy, Love, Vigor, and Excitement) were constructed based on results of the factor analysis. Confirmatory factor analyses confirmed the measurement model. In study 2, the reliability and construct validity of each of the 15 factor-derived scales was assessed in both referred and non-referred college students. Study 3 investigated the utility of the COPAS scales in differentiating referred and non-referred college students. Results indicated that reliability of the scales was good to excellent, while convergent and divergent validity was good for most scales. The COPAS scales were also shown to differentiate between referred and non-referred samples of college students. Overall, the COPAS was shown to be suitable for research with college student populations.

A preliminary comparison of flat affect schizophrenics and brain-damaged patients on measures of affective processing.

Flat affect is a major component of schizophrenia and is often also seen in neurological disorders. A preliminary set of comparisons were conducted to delineate neuropsychological mechanisms underlying flat affect in schizophrenia, and new measures are described for the assessment of affective deficits in clinical populations. Subjects were schizophrenic with flat affect (SZs), right brain-damaged (RBD), Parkinson's Disease (PDs), and normal control (NC) right-handed adults. Subjects were administered affective measures of expression and perception in both facial and vocal channels. For both perceptual and expressive tasks the SZs performed significantly less accurately than the NCs and the PDs but did not differ from the RBDs. This was the case for both face and voice. This finding lends support to the speculation that right hemisphere mechanisms, especially cortical ones, may be compromised among schizophrenics with flat affect.
