Aerobic Exercise and Creative Potential: Immediate and Residual Effects

The potential effects of aerobic exercise on creative potential were explored both immediately following moderate aerobic exercise and after a 2-hr lag. Sixty college students participated in an experiment consisting of 3 regimens varying the time when a Torrance Test of Creative Thinking was taken in relation to exercise completion. The results supported the hypotheses that creative potential will be greater on completion of moderate aerobic exercise than when not preceded by exercise (immediate effects), that creative potential will be greater following a 2-hr lag time following exercise than when not preceded by exercise (residual effects), and that creative potential will not be significantly different immediately following exercise than after a 2-hr lag time following exercise (enduring residual effects). Limitations and implications for future research were discussed.     

Longitudinal Analysis of Associations between 3-D Mental Rotation and Mathematics Reasoning Skills during Middle School: Across and within Genders

ABSTRACT

The development of math reasoning and 3-d mental rotation skills are intertwined. However, it is currently not understood how these cognitive processes develop and interact longitudinally at the within-person level – either within or across genders. In this study, 553 students (52% girls) were assessed from fifth to seventh grades on 3-d mental rotation spatial skills (assessed each fall) and numerical and algebraic math reasoning skills (assessed each spring). Boys outperformed girls on mental rotation tests across all three grades, and on fifth and seventh grade math reasoning tests. Consistent with the literature on between-person comparisons, there was a positive correlation between mental rotation and math reasoning skills in the full sample and for both genders. A random intercept cross-lagged panel model was used to control for these confounding group-level differences in order to isolate within-person associations between earlier and later performance. Initially in fifth grade, math reasoning predicted subsequent sixth grade mental rotation skills. By seventh grade, more advanced mental rotation skills were associated with subsequent math reasoning skills while math reasoning skills were no longer predictive of mental rotation skills. An examination of gender differences revealed that this pattern was driven by boys while girls experienced less within-person change. These findings suggest that boys may initially rely in part on their math reasoning skills to solve 3-d mental rotation tasks. However, as their 3-d mental rotation skills mature, they begin to primarily depend upon these developing spatial skills to solve math reasoning problems rather than the reverse.     

Shame,posttraumatic stress disorder,and intimate partner violence perpetration

Drawing from theoretical and empirical literature linking shame to aggression and violence, the authors propose that shame may be an important variable to examine in studies of posttraumatic stress disorder (PTSD) and intimate partner violence (IPV) perpetration. The authors review the literature linking shame, PTSD, and IPV, propose ideas for future research, and suggest that shame and shame regulation may be a useful target of clinical interventions aimed at violence perpetrators.     

Surviving Abuse: Shame,Anger, Forgiveness

The issue of forgiveness affects everyone at some time or another; whether young or old, male or female, Christian or not. For the survivor of abuse, the issue of forgiveness journeys with them profoundly influencing their life, their recovery, and even their faith. Surviving Abuse: Shame, Anger, Forgiveness is an attempt to develop a theology of forgiveness from the perspective of a survivor of abuse.     

Screening for Significant Behavior Problems in Diverse Young Children Living in Poverty

The development and use of first line screening instruments is an essential first step in assessing behavior disorders in very young children. The Early Childhood Behavior Screen (ECBS) is a parent-report measure for behavior disorders and is normed on young children (1–5 years old) living in poverty. The current study presents psychometric support for the discriminative validity of the ECBS’s 10-item Challenging Behavior Scale (CBS) as a first-line screener for externalizing behavior problems for preschool aged-children in poverty. The study’s sample included 673 participants (M age years = 2.81; 63.2 % male; 65.8 % African American) that all met the federal definitional standard for living in poverty. A confirmatory factor analysis was run to provide support for the ECBS factor structure. Receiver operating characteristics (ROC) curve analyses were used to test the CBS’s ability to distinguish between 428 clinic-referred children and 245 non-clinic-referred children. Results showed an acceptable fit model for the ECBS, providing further evidence of its construct validity. Optimal cut-scores by child age derived from the ROC curve analyses were provided with corresponding levels of sensitivity, specificity, and positive and negative predictive values. Sensitivity rates for cut scores ranged from 0.76 to 0.83 and specificity rates ranged from 0.88 to 0.95. Acceptable test–retest reliability and good internal consistency also was observed. The CBS quickly identifies young children from low-income, urban, diverse populations that may be at-risk for developing significant behavior disorders and should be considered by health care professionals who work with very young children.     

Candidate Voice Pitch Influences Election Outcomes

A growing literature in psychology shows that human voice pitch—perceived “highness” or “lowness” as determined by the physiology of the throat—influences how speakers are perceived. This leads to the prediction that candidate voice pitch influences voters. Here this question is addressed with two studies. The first is an experiment conducted with a large national sample of U.S. adults. The results show that men and women prefer to vote for male and female candidates with lower pitched voices. The second study examines the outcomes of the 2012 U.S. House elections. When facing male opponents, candidates with lower voices won a larger vote share. However, when facing female opponents, candidates with higher voices were more successful and particularly so in the case of male candidates. In synthesizing research on the human voice and voter behavior and triangulating evidence from a controlled experiment and a large observational study of actual elections, this article illustrates that candidate voice pitch influences election outcomes.     

Correlations Between Handshape and Movement in Sign Languages

Sign language phonological parameters are somewhat analogous to phonemes in spoken language. Unlike phonemes, however, there is little linguistic literature arguing that these parameters interact at the sublexical level. This situation raises the question of whether such interaction in spoken language phonology is an artifact of the modality or whether sign language phonology has not been approached in a way that allows one to recognize sublexical parameter interaction. We present three studies in favor of the latter alternative: a shape-drawing study with deaf signers from six countries, an online dictionary study of American Sign Language, and a study of selected lexical items across 34 sign languages. These studies show that, once iconicity is considered, handshape and movement parameters interact at the sublexical level. Thus, consideration of iconicity makes transparent similarities in grammar across both modalities, allowing us to maintain certain key findings of phonological theory as evidence of cognitive architecture.
