Coping and academic problem-solving ability in test anxiety.

The present study examined coping tendencies and perceptions of problem-solving ability in test anxiety. A sample of 125 students completed the revised Ways of Coping Questionnaire, the Academic Problem-Solving Inventory, and measures of state and trait test anxiety. Correlational analyses confirmed that emotion-focused coping (i.e., avoidant and confrontive coping) was associated positively with test anxiety. Also, test-anxious individuals reported poorer ability to solve academic problems. Finally, regression analyses revealed that coping tendencies and perceived problem-solving ability predicted unique variance in test-anxiety scores. The results are discussed in terms of the need for a multidimensional model of test anxiety that includes coping processes and self-evaluations of problem-solving ability.

Depression, problem-solving ability, and problem-solving appraisals.

Behavioral analytic methods were used to create a college student version of the Means Ends Problem Solving Procedure (MEPS). This instrument then was administered with measures of perceived problem-solving ability to depressed and nondepressed students to determine whether differences exist in both problem-solving ability and problem-solving appraisal. Analyses revealed that depressed subjects had more negative expectations and lower appraisals of their problem-solving ability. However, the groups did not differ in terms of the actual quality of their behavioral solutions to interpersonal, intrapersonal, and emotional problem situations. The results are interpreted as support for the role of cognitive factors in depression and problem-solving across a range of problem-solving situations.

Within-subject control designs and voluntary bidirectional control of cardiac rate: methodological comparison between pre-experiment and pretrial baselines.

The purpose of this study was to compare two methods of analyzing the effects of exteroceptive feedback training on the voluntary bidirectional control of human cardiac rate with the use of a within-subject control design. In this design heart rate (HR) during an experimental period (increase or decrease) is compared with that recorded during some other control period, generally a baseline "rest" period. Ten male undergraduates were instructed to control HR and given visual feedback of heart activity. Trials on which Ss were to raise and to lower HR were both given in a single training session. The data were analyzed in two ways: (a) cardiac rate during HR control periods was compared to an initial pre-experimetn baseline; (b) cardiac rate during HR control periods was compared to a running pretrial baseline. The results support the argument that the former procedure fails to take account of habituating levels of cardiac rate and favors finding large magnitude decreases in HR but small increases, whereas the latter procedure favors finding large magnitude increases but small decreases. It is suggested that magnitude of directional control will be artifactual when initial values are used to assess change. Contaminating influences on the running pretrial baseline were also discussed.

Relationships between Spielberger trait anxiety and Lykken social and physical trait anxiety.

To determine the relationship between Spielberger's measure of trait anxiety and social-interpersonal vs. physical danger trait anxiety, Ss were administered and trait scale of the State-Trait Anxiety Inventory (STAI) and Lykken's Activity Preference Questionnaire (APQ). Results of correlative analyses indicated that the STAI-Trait measure correlated significantly with APQ-Social Anxiety, but not with APQ-Physical Anxiety. Results were discussed in terms of the implications for predicting state anxiety in different situations by the use of unidimensional vs. multidimensional trait anxiety measures.

Note on relation of autonomic perception to voluntary control of heart rate.

Relationships between subscores of the Autonomic Perception Questionnaire and ability to raise and lower heart rate voluntarily were examined in 40 subjects. Subscores which reflected autonomic awareness in anxiety and pleasure states were not predictive of degree of cardiac control, while the subscore specific to reported awareness of heart functioning during pleasure states only was positively correlated with ability to raise heart rate.

The sensation seeker and anxiety reactivity: relationships between the sensation-seeking scales and the activity preference questionnaire.

The five scales of the Zuckerman Sensation-Seeking Scale and Lykken's Activity Preference Questionnaire were administered to 83 male and female college students to test the hypothesis that there is an inverse relationship between sensation seeking and anxiety reactivity. The data were intercorrelated separately for males and females. Results were, in general, consistent with expectations: individuals high in optimal level of stimulation are low in anxiety reactivity in situations that involve physical danger and in situations related to social fears or embarrassment. This relationship was found for most of the dimensions of sensation seeking for males, but was confined to specific subscales for females.
