A multicomponent investigation of the interaction of generalized anxiety and phobia

Forty female undergraduates forming four groups, high or low trait anxiety with or without a specific fear (rats), participated in a psychophysiological assessment of their response to the phobic object, a neutral object (rabbit), and to a general anxiety-induction procedure (threat of shock). Subjects also completed a number of tasks requiring sustained attention. Blood samples were drawn to determine thyroid hormone (T3 and T4) levels. Trait anxiety was found to interact with specific fear in response to the feared object. The high-trait anxious/high-fear group was most physiologically responsive to the rat. Trait- anxious subjects were more responsive to the threat of shock and showed performance deficits on reaction time, vigilance, and backward digit span tasks. These subjects also had significantly higher T3 and T4 levels. The findings are discussed with regard to the role of general anxiety in the etiology and/or maintenance of specific fears and the role of thyroid hormones in accentuating physiological response to feared stimuli.     

Job Seeking Among Retirees Seeking Bridge Employment

Using a sample of recent retirees, the study described here sought to test the general propositions of the Wanberg, Watt, and Rumsey (1996) model by (a) including specific variables that are likely to be relevant to older adults seeking work after retirement (bridge employment) and (b) integrating more recent variable groups (e.g., situational constraints) suggested by recent research (e.g., Wanberg, Kanfer, & Rotundo (1999) and Kanfer, Wanberg, & Kantrowitz (2001) . Generally, the results support the efficacy of the Wanberg et al. model to predict job seeking among this group. Biographical variables such as older worker job search constraints, self-evaluations (e.g., job seeking self-efficacy), and motive/social variables (e.g., social support) were related to job seeking. Some of these, however, were not in the expected direction. Similarities and differences between "regular" job seeking and bridge employment job seeking are discussed.     

Dehumanizing but competent: The impact of gender,illness type,and emotional expressiveness on patient perceptions of doctors

This study is the first attempt to investigate men's and women's anticipated reactions to a consultation with a doctor holding either a dehumanizing or humanistic approach to patient treatment. Participants (N = 375) read a vignette depicting a doctor's treatment philosophy—emphasizing either the metaphor of the body as a machine (dehumanizing condition) or emphasizing individual humanness (humanizing condition). They then imagined consulting the doctor about a psychological or physical illness. Although, medical dehumanization had undesirable consequences, some men rated the dehumanizing doctor as more competent than the humanizing doctor. These were men who were (a) emotionally expressive and seeking help for a psychological illness, and (b) men low in emotional expressiveness seeking help for a physical illness.     

Empirical evidence and the knowledge-that/knowledge-how distinction

In this article I have two primary goals. First, I present two recent views on the distinction between knowledge-that and knowledge-how (Stanley and Williamson, The Journal of Philosophy 98(8):411–444, 2001; Hetherington, Epistemology futures, 2006). I contend that neither of these provides conclusive arguments against the distinction. Second, I discuss studies from neuroscience and experimental psychology that relate to this distinction. Having examined these studies, I then defend a third view that explains certain relevant data from these studies by positing the double dissociation of knowledge-that and knowledge-how and that is also able to do explanatory work elsewhere.     

Temperament Pathways to Childhood Disruptive Behavior and Adolescent Substance Abuse: Testing a Cascade Model

Temperament traits may increase risk for developmental psychopathology like Attention-Deficit/Hyperactivity Disorder (ADHD) and disruptive behaviors during childhood, as well as predisposing to substance abuse during adolescence. In the current study, a cascade model of trait pathways to adolescent substance abuse was examined. Component hypotheses were that (a) maladaptive traits would increase risk for inattention/hyperactivity, (b) inattention/hyperactivity would increase risk for disruptive behaviors, and (c) disruptive behaviors would lead to adolescent substance abuse. Participants were 674 children (486 boys) from 321 families in an ongoing, longitudinal high risk study that began when children were 3 years old. Temperament traits assessed were reactive control, resiliency, and negative emotionality, using examiner ratings on the California Q-Sort. Parent, teacher, and self ratings of inattention/hyperactivity, disruptive behaviors, and substance abuse were also obtained. Low levels of childhood reactive control, but not resiliency or negative emotionality, were associated with adolescent substance abuse, mediated by disruptive behaviors. Using a cascade model, family risk for substance abuse was partially mediated by reactive control, inattention/hyperactivity, and disruptive behavior. Some, but not all, temperament traits in childhood were related to adolescent substance abuse; these effects were mediated via inattentive/hyperactive and disruptive behaviors.

Money can’t buy love: Asymmetric beliefs about gift price and feelings of appreciation

Across three studies, we identify an asymmetry between gift-givers’ and gift-recipients’ beliefs about the link between gift price and feelings of appreciation. Gift-givers expected a positive correlation between how much they spent on a gift and the extent to which gift-recipients would appreciate the gift because gift-givers assume that more expensive gifts convey a higher level of thoughtfulness. Gift-recipients, in contrast, reported no such association between gift price and their actual feelings of appreciation. This effect occurred regardless of whether the individual’s role and the magnitude of the gift were manipulated or measured in the field. Taken together, these findings cast doubt on whether gift-givers can draw on their personal experience as gift-recipients in order to identify meaningful gifts for others.     

The cultural grounding of personal relationship: Friendship in North American and West African worlds

This study considers how different constructions of self and social reality influence the experience of relationship. Reflecting the relational interdependence of West African worlds, the authors hypothesized and observed that Ghanaian participants were significantly more likely than U.S.A. participants (ns = 50 each) to advocate caution toward friends and to emphasize practical assistance in friendship. Reflecting the atomistic independence of North American worlds, the authors hypothesized and observed that U.S.A. participants were significantly more likely than Ghanaian participants to indicate a large friendship network; to emphasize companionship, particularly relative to Ghanaian women; and to emphasize emotional support, particularly relative to Ghanaian nonstudents. Results suggest that friendship is not a universal form; instead, it takes different forms in different cultural worlds.     

Type A as a Moderator of Stressors and Job Complexity: A Comparison of Achievement Strivings and Impatience-Irritability

This study examined two components (achievement strivings and impatience-irritability) of the Type A Behavior Pattern as moderators of job stressors and job complexity on health and job satisfaction. It was predicted that achievement strivings would moderate the impact of job stressors and impatience-irritability would impact responses to job complexity. Data from 525 employed adults provided mixed support for the moderator hypotheses. Relations between job stressors and both health and job satisfaction were strongest among employees reporting high levels of achievement strivings. Impatience-irritability had no moderating effect. For job complexity, only one moderator effect was found. Mental demands were positively related to job satisfaction among those reporting low levels of impatience-irritability. Implications of these findings are discussed.     

Observation of high and low passive ankle flexibility in stair descent

Able-bodied people from the two extremes of the distribution of passive dorsiflexion exhibit biomechanical differences when descending stairs. Whether physical therapists could judge accurately the amount of ankle flexibility from observation of stair descent was examined with physical therapists (20 neurological 20 cardiothoracic) and 20 students. Subjects were 18 able-bodied men with high or low passive dorsiflexion. Raters viewed videotaped subjects descending stairs at normal playback speed and in slow motion and rated ankle flexibility on a 20-point scale. 'Flexible' or 'inflexible' subjects were classified correctly better than chance, but accuracy of rating flexibility was relatively poor. Both experience and slow motion playback improved accuracy. Physical therapists can detect extremes of normal flexibility in the ankle, based solely on observation of stair descent, and experienced therapists are better at this task than less experienced ones. Using slow motion videotape enhanced observational analysis.
