Examining the effects of postural constraints on estimating reach

The tendency to overestimate has consistently been reported in studies of reachability estimation. According to one of the more prominent explanations, the postural stability hypothesis, the perceived reaching limit depends on the individual's perceived postural constraints. To test that proposition, the authors compared estimates of reachability of 38 adults (a) in the seated posture (P1) and (b) in the more demanding posture of standing on one foot and leaning forward (P2). Although there was no difference between conditions for total error, results for the distribution and direction of error indicated that participants overestimated in the P1 condition and underestimated in the P2 condition. It therefore appears that perceived postural constraints could be a factor in judgments of reachability. When participants in the present study perceived greater postural demands, they may have elected to program a more conservative strategy that resulted in underestimation.     

Prefrontal cognitive ability, intelligence, Big Five personality, and the prediction of advanced academic and workplace performance

Studies 1 and 2 assessed performance on a battery of dorsolateral prefrontal cognitive ability (D-PFCA) tests, personality, psychometric intelligence, and academic performance (AP) in 2 undergraduate samples. In Studies 1 and 2, AP was correlated with D-PFCA (r=.37, p<.01, and r=.33, p<.01, respectively), IQ (r=.24, p<.05, and r=.38, p<.01, respectively), and Conscientiousness (r=.26, p<.05, and r=.37, p<.01, respectively). D-PFCA remained significant in regression analyses controlling for intelligence (or g) and personality. Studies 3 and 4 assessed D-PFCA, personality, and workplace performance among (a) managerial-administrative workers and (b) factory floor workers at a manufacturing company. Prefrontal cognitive ability correlated with supervisor ratings of manager performance at values of r ranging from .42 to .57 (ps<.001), depending on experience, and with factory floor performance at pr=.21 (p=.02), after controlling for experience, age, and education. Conscientiousness correlated with factory floor performance at r=.23.     

Effects of Parent’s Gender, Child’s Gender, and Parental Involvement on the Academic Achievement of Adolescents in Single Parent Families

We used a national database (Educational Longitudinal Study) to investigate the effects of parent’s gender, child’s gender, and parental involvement in school on the academic achievement of adolescents in single-parent families. A three way 2 × 2 × 2 (parent’s gender × child’s gender × parental involvement) MANCOVA was conducted with four student academic achievement indicators as dependent variables and SES as a covariate. The results indicated that parent gender and child gender interact with parent involvement to affect adolescents’ academic achievement differentially. Specifically, daughters who lived with highly involved single-fathers performed better academically than the other groups did. These findings suggest that researchers who study single-parents’ involvement in their adolescents’ academic achievement need to pay more attention to gender-specific effects.     

Presuicide attempt communications between parasuicides and consulted caregivers.

A high percentage of parasuicides visit professional caregivers prior to the attempted suicide. The content or outcome of these consultations is unknown. We interviewed hospitalized attempters and the professional caregivers they identified as having been consulted prior to their attempts. About half of these patients directly disclosed suicidal symptoms or intentions, especially to mental health professionals. These professionals more often inquired about suicidal ideations than did nonpsychiatric physicians. However, few caregivers noted suicidal thinking or probed suicidal symptoms. The data suggest that professional caregivers and especially nonpsychiatric physicians should be more sensitive and responsive to the signs and symptoms of suicidality.     

Sender Demeanor: Individual Differences in Sender Believability Have a Powerful Impact on Deception Detection Judgments

Sender demeanor is an individual difference in the believability of message senders that is conceptually independent of actual honesty. Recent research suggests that sender demeanor may be the most influential source of variation in deception detection judgments. Sender demeanor was varied in five experiments (N = 30, 113, 182, 30, and 35) to create demeanor–veracity matched and demeanor–veracity mismatched conditions. The sender demeanor induction explained as much as 98% of the variance in detection accuracy. Three additional studies (N = 30, 113, and 104) investigated the behavioral profiles of more and less believable senders. The results document the strong impact of sender effects in deception detection and provide an explanation of the low‐accuracy ceiling in the previous findings.     

Building Models for the Relationship Between Attitudes Toward Suicide and Suicidal Behavior: Based on Data from General Population Surveys in Sweden,Norway, and Russia

Our aim was to build a model delineating the relationship between attitudes toward suicide and suicidal behavior and to assess equivalence by applying the model on data from different countries. Representative samples from the general population were approached in Sweden, Norway, and Russia with the Attitudes Toward Suicide (ATTS) questionnaire. Data on experience of suicidal behavior among significant others and self‐reported suicidal expressions were also collected. Structural equation modeling resulted in gender and country specific models where experience of suicidal behavior among significant others and self‐reported suicidal expressions earlier in life predicted attitudes, and attitudes predicted current suicidal expressions. The models included the attitude factors acceptance of suicide, condemnation, and preventability; age and level of education were also incorporated. The different models reveal possible ways to better understand gender and culture‐specific paths between attitudes and suicidal behaviors, and their relevance in a suicide prevention context is considered.
