The Impact of the Family Environment on the Ethnic Identity Development of Multiethnic College Students

In this qualitative study of 5 multiethnic college students, the findings indicate that family environment played a significant role in the participants' ability to develop secure ethnic identities. The participants who described their family members as supportive of their multiple ethnic backgrounds also felt confident about their ethnic identity, whereas the participants who described their family members as unsupportive of their multiple ethnic backgrounds maintained that they often felt insecure about their ethnic identity.     

The Effects of Stereotyping and Implicit Theory on Benevolent Prejudice Toward Aboriginal Canadians

Stereotyping and implicit theory on benevolent prejudice toward an Aboriginal student were investigated in a mock work setting. In a 2 (Stereotype: prime vs. no prime) × 2 (Theory: entity vs. incremental) × 2 (Race: Aboriginal vs. Caucasian) between‐subjects design, non‐Aboriginal participants were primed or not primed with a negative Aboriginal stereotype and an entity or incremental implicit theory before evaluating an Aboriginal or Caucasian student. Consistent with a benevolent prejudice perspective, when primed with the stereotype, only participants holding an entity theory expressed greater desire to help the Aboriginal compared to the Caucasian candidate, despite both candidates demonstrating identical performance information. Implications for prejudice in work environments are discussed.     

How do I feel about the behavior? The interplay of affective associations with behaviors and cognitive beliefs as influences on physical activity behavior.

Individuals have affective associations with health behaviors. In other domains such associations have been shown to influence behavior, but affective associations with health behaviors are not included in current health decision-making models. The authors examined whether affective associations with exercise predicted individuals' activity behavior and, if so, how they interfaced with other decision-making constructs to influence behavior. Adult participants (N = 433) reported their current physical activity behavior and affective associations with physical activity. Health belief model and theory of planned behavior constructs were also assessed. More positive affective associations with activity significantly predicted greater activity behavior. Moreover, the influence of the health belief model and theory of planned behavior constructs on activity behavior was mediated through affective associations. Affective associations were shown to play a central role in individuals' activity behavior, both as a mediator of the effects of cognitively based decision-making factors and as an independent predictor of activity behavior. The results suggest the need to include affective influences on behavior in formal models of health decision making and, potentially, to explore affectively based intervention routes to change behaviors.     

Dyad Practice Impacts Self-Directed Practice Behaviors and Motor Learning Outcomes in a Contextual Interference Paradigm

We studied dyad practice to determine whether and how alternating practice blocks with a partner impacts self-directed practice scheduling, learning, and perceptions of practice. Participants were assigned to be Partner 1 (P1) or 2 (P2). P1s had a blocked, random, or self-directed schedule, while all P2s self-directed practice of 3, differently-timed keystroke-sequences. P2s showed both own error-dependent practice (switching sequences following better performance) and partner-dependent practice, with the partner's schedule impacting sequence selection and switching frequency. A partner's schedule also impacted learning. Random practice resulted in better timing accuracy than blocked practice for both partners in an immediate and delayed retention test. These data give evidence that self-directed practice behaviors and learning outcomes are modulated by a partner's practice schedule.     

Posttraumatic stress and depression: potential pathways to disease burden among heart failure patients

Background and Objectives: Posttraumatic stress disorder (PTSD) and Major Depressive Disorder (MDD) are associated with high disease burden. Pathways by which PTSD and MDD contribute to disease burden are not understood. Design: Path analysis was used to examine pathways between PTSD symptoms, MDD symptoms, and disease burden among 251 low-income heart failure patients. Methods: In Model 1, we explored the independent relationship between PTSD and MDD symptoms on disease burden. In Model 2, we examined the association of PTSD symptoms and disease burden on MDD symptoms. We also examined indirect associations of PTSD symptoms on MDD symptoms, mediated by disease burden, and of PTSD symptoms on disease burden mediated by MDD symptoms. Results: Disease burden correlated with PTSD symptoms (r = .41; p < .001) and MDD symptoms (r = .43; p < .001) symptoms. Both models fit the data well and displayed comparable fit. MDD symptoms did not mediate the association of PTSD symptoms with disease burden. Disease burden did mediate the relationship between PTSD symptoms and MDD symptoms. Conclusions: Results support the importance of detection of PTSD in individuals with disease. Results also provide preliminary models for testing longitudinal data in future studies.     

Expert testimony on malingering: The admissibility of clinical procedures for the detection of deception

The detection of malingering in the legal context frequently requires the use of psychiatric and psychological expert testimony. These experts may rely on certain clinical techniques in order to detect deception. This article addresses the problem of the admissibility in evidence of clinical procedures used by these experts. The scientific reliability and effect on constitutional rights of procedures such as hypnosis, polygraphy, “truth” drugs, and psychological tests is examined.     

Infant sensitivity to audiovisually coherent events

Summary We examined 5-month-old infants' sensitivity to audiovisually coherent and incoherent events. A person speaking and an automobile with engine running were filmed approaching and receding with corresponding (coherent) soundtracks. Infants were tested with a habituation paradigm in which they observed coherent or incoherent films, involving, respectively, acoustical radial motion in the direction seen or opposite to the direction seen. Infants habituated to both person and car films, but coherent events uniformly yielded more rapid habituation than did incoherent ones. In addition, infants treated silent events more like audiovisual coherence than like incoherence. Infants habituated more to cars than to people, suggesting that a speaking person may especially maintain infant attention.
