Anxiety,aspirations, and self-concept in the achievement process: A longitudinal model with latent variables

Recent research suggests that anxiety is not a single, unified reaction to perceived threat, but rather a cluster of interrelated factors whose relationships to performance change as the individual progresses from one test event to another. This study investigated the presumed linkages between traitlike predispositions to perceive threat and achievement performance, as mediated by statelike anxiety arousal on a longitudinal basis (Perceived Threat Anxiety Arousal Impaired Performance). College students were administered self-report questionnaire measures during a preenrollment period, after the first two midterms, and following the last two midterms in a general psychology course. Four performance measures and 26 motivational indicators were fitted to a 10-factor latent model using LISREL model-fitting techniques. Path-analytic interpretations of this structural model provided little evidence for the commonly held view that traitlike threat perceptions mediate performance via statelike anxiety reactions. Far more promising, theoretically, are those influences on test performance stemming from the self-attributional, cognitive domain. Overall, the findings support a recent reinterpretation of achievement anxiety as stemming from the disruptive effects of diminished ability perceptions (and hence, impaired personal worth), rather than from the interfering influence of diffused emotional arousalper se.     

Coping as a mediator between personality and stress outcomes: a longitudinal study with cataract surgery patients

Personality and coping were specified as predictors of emotional outcomes of a mildly stressful medical procedure. Situation-specific coping was examined in contrast to dispositional coping, and it was tested whether one or the other would mediate the relationship between higher-order personality factors and stress outcomes. Cataract patients (N=110) participated at four measurement points in time during a six-week period surrounding their scheduled surgery. Dispositional coping did not mediate the personality–outcome relationship. In contrast, situation-specific coping acquired a mediator status between personality and adaptational criteria and accounted for independent outcome variance once personality traits were included as predictors in the models. Thus, the data suggest that whether or not coping mediates between personality factors and affective outcomes may be related to the methodological approaches of its operationalization.

Changing views about personality disorders: Comment about the prospective studies CIC, CLPS, and MSAD

Three large-scale prospective studies (Children in the Community Study [CIC; Cohen, Crawford, Johnson, & Kasen, this issue], Collaborative Longitudinal Personality Disorders Study [CLPS; Skodol et al., this issue], and the McLean Study of Adult Development [MSAD; Zanarini, Frankenburg, Hennen, Reich, & Silk, this issue]) are discussed with respect to the following issues: shared and complementary features of the study designs, evidence for stable and changing personality disorder features, methodological issues (reliability, stability, and invariance), the relationship between Axis I and II disorders, and dimensional versus categorical representations of personality disorders.     

Immediate and delayed recall of visually presented sentences: evidence for the involvement of phonological information

The lure intrusion effect refers to the observation that lexical priming affects recall of sentences. This effect is taken as evidence against the contribution of surface information, even with immediate sentence recall. Recently, Rummer and Engelkamp (2003a) demonstrated that this effect, which is usually observed under rapid serial visual presentation (RSVP), does not appear under immediate recall of auditorily presented sentences. This finding indicates that surface information (i.e., phonological or acoustic-sensory information) can contribute to immediate sentence recall. So far, however, the findings do not allow for a decision on whether phonological and/or acoustic-sensory information is used in immediate sentence recall. In order to dissociate the two kinds of surface information, an experiment was conducted in which immediate and delayed recall were tested for sentences that were visually presented for a longer period of time than in RSVP. This kind of presentation should support phonological representations, but does not allow for acoustic-sensory representations. The findings showed a smaller intrusion effect for immediate than for delayed recall. This indicates that, if available, phonological information is involved in immediate sentence recall thereby reducing the lure intrusion effect. Furthermore, the findings support the assumption that the phonological trace provided via RSVP reading is weaker than in normal reading.

Translating intentions into sunscreen use: an interaction of self-efficacy and appearance norms

The study examines whether self-efficacy mediates between intention and behavior, and whether appearance norms and self-efficacy are additive or synergistic predictors of sunscreen use. At two measurement points in time, 14 weeks apart, 154 individuals responded to an online questionnaire. Moderated mediation was tested by hierarchical regression analyses. Self-efficacy mediated the intention-behavior relationship, whereas appearance norms emerged as a moderator of the self-efficacy-sunscreen use relationship. The model accounted for 22% of the behavior variance at time 2. For individuals who believe that they would look more attractive with a tan, self-efficacy did not have a strong effect on behavior. Thus, for skin-protection motivation to become effective, self-efficacy is needed in conjunction with less positive appearance norms. Implications for public health promotion and mass media sunscreen use campaigns are discussed.
