Anthropometric design criteria: correction variables for military aircraft

Significant errors in the application of dimensional anthropometric design criteria for tactical military aircraft cockpits have been identified. These errors result from insufficient consideration of previously undefined variables relative to posture, restraint system items, and aviators' personal protection equipment as discussed by McConville and Laubach in 1978.     

A dynamic developmental theory of attention-deficit/hyperactivity disorder (ADHD) predominantly hyperactive/impulsive and combined subtypes

Attention-deficit/hyperactivity disorder (ADHD) is currently defined as a cognitive/behavioral developmental disorder where all clinical criteria are behavioral. Inattentiveness, overactivity, and impulsiveness are presently regarded as the main clinical symptoms. The dynamic developmental behavioral theory is based on the hypothesis that altered dopaminergic function plays a pivotal role by failing to modulate nondopaminergic (primarily glutamate and GABA) signal transmission appropriately. A hypofunctioning mesolimbic dopamine branch produces altered reinforcement of behavior and deficient extinction of previously reinforced behavior. This gives rise to delay aversion, development of hyperactivity in novel situations, impulsiveness, deficient sustained attention, increased behavioral variability, and failure to "inhibit" responses ("disinhibition"). A hypofunctioning mesocortical dopamine branch will cause attention response deficiencies (deficient orienting responses, impaired saccadic eye movements, and poorer attention responses toward a target) and poor behavioral planning (poor executive functions). A hypofunctioning nigrostriatal dopamine branch will cause impaired modulation of motor functions and deficient nondeclarative habit learning and memory. These impairments will give rise to apparent developmental delay, clumsiness, neurological "soft signs," and a "failure to inhibit" responses when quick reactions are required. Hypofunctioning dopamine branches represent the main individual predispositions in the present theory. The theory predicts that behavior and symptoms in ADHD result from the interplay between individual predispositions and the surroundings. The exact ADHD symptoms at a particular time in life will vary and be influenced by factors having positive or negative effects on symptom development. Altered or deficient learning and motor functions will produce special needs for optimal parenting and societal styles. Medication will to some degree normalize the underlying dopamine dysfunction and reduce the special needs of these children. The theory describes how individual predispositions interact with these conditions to produce behavioral, emotional, and cognitive effects that can turn into relatively stable behavioral patterns.     

The Tromsø Social Intelligence Scale, a self-report measure of social intelligence

Social intelligence is a construct that not only appeals to laymen as a relevant individual difference but also has shown promising practical applications. Nevertheless, the use of social intelligence in research and applied settings has been limited by definitional problems, difficulties in empirically differentiating social intelligence from related constructs, and the complexity of most existing measures of social intelligence. The goal of the present research was to address some of these obstacles by designing a multi‐faceted social intelligence measure that is short and easy to administer. Three studies were conducted to develop and validate the Tromsø Social Intelligence Scale (TSIS). Study 1 examined professional psychologists’ interpretations of social intelligence to derive a consensually agreed‐upon definition of the construct. In Study 2, a large pool of social intelligence items were tested, and a 3‐factor, 21‐item scale was identified. In Study 3, the stability of this measure was confirmed.     

Genetic and environmental contributions to the co-occurrence of depressive personality disorder and DSM-IV personality disorders

One of the main controversies with regard to depressive personality disorder (DPD) concerns the co-occurrence with the established DSM-IV personality disorders (PDs). The main aim of this study was to examine to what extent DPD and the DSM-IV PDs share genetic and environmental risk factors, using multivariate twin modeling. The DSM-IV Structured Interview for Personality was applied to 2,794 young adult twins. Paranoid PD from Cluster A, borderline PD from Cluster B, and all three PDs from Cluster C were independently and significantly associated with DPD in multiple regression analysis. The genetic correlations between DPD and the other PDs were strong (.53-.83), while the environmental correlations were moderate (.36-.40). Close to 50% of the total variance in DPD was disorder specific. However, only 5% was due to disorder-specific genetic factors, indicating that a substantial part of the genetic vulnerability to DPD also increases the vulnerability to other PDs.     

The Bull's-Eye Values Survey: A Psychometric Evaluation

Two studies were conducted to develop and evaluate an instrument intended to identify and measure personal values, values attainment, and persistence in the face of barriers. Study 1 describes a content validity approach to the construction and preliminary validation of the Bull's Eye Values Survey (BEVS), using a sample of institutionalized patients suffering from epilepsy. Study 2 investigated the psychometric properties of the BEVS with a sample of Swedish university students. Results suggest that the BEVS is sensitive to treatment effects and can differentiate between clients who receive values-based interventions and those who do not. The BEVS subscales and total score appear to measure an independent dimension of psychological functioning that is negatively correlated with measures of depression, anxiety, and stress, and positively correlated with a measure of psychological flexibility. The BEVS also exhibits acceptable temporal stability and internal consistency. The study provides preliminary support for the BEVS as both a research and clinical tool for measuring values, values-action discrepancies, and barriers to value-based living.     

The flip side of vanity sizing: How consumers respond to and compensate for larger than expected clothing sizes

Vanity sizing has become a popular retail trend and recent work shows it has a favorable impact on consumers. However, as the current research demonstrates, significant variations in sizing standards across retailers mean that consumers are as likely to encounter larger sizes as they are smaller, “vanity” sizes when shopping, highlighting the importance of understanding how consumers react to this potential threat in the marketplace. Across five studies we demonstrate that larger sizes result in negative evaluations of clothing and show that these effects are driven by consumers' appearance self-esteem. Importantly, we also find that instead of unilaterally lowering purchase intent as one might assume, larger sizes can actually increase spending, as consumers engage in compensatory consumption to help repair their damaged self-esteem. In so doing, this research reveals a dynamic and complex relationship between consumers and sizing labels, where shopping can serve to build, strengthen, threaten, and/or repair appearance self-esteem.

Relationship quality,divorce, and well-being: Findings from a three-year longitudinal study

Recent studies indicate that divorce sometimes is positive for subjective well-being, but we lack knowledge about the circumstances under which this is the case. Further, we lack knowledge about the possible different associations between divorce and life satisfaction (LS) vs. positive affect (PA). The current study is based on the Norwegian Mother and Child Cohort Study (MoBa). Change in LS and PA over a three-year period was examined in women who divorced and women who did not divorce (N > 37,000). Relationship quality and relationship status at follow-up were included in the models. The results indicated that divorce predicted higher LS and PA when initial relationship quality was poor. Furthermore, divorce predicted higher PA for women who, after divorce, reported being in a new romantic relationship. The associations between relationship quality and LS and PA were stronger among not-divorced than divorced women, indicating that relationship quality affects LS and PA.
