A note on reflex sensitivity and formation of conditioned responses

The relationship between ease of conditioning and reflex sensitivity was examined in the GSR and blink reflex under two experimental conditions. Significant positive correlations were obtained between a variety of response characteristics (e.g. frequency, amplitude of blink, spontaneous GSRs) and the number of conditioned responses, thus supporting earlier findings obtained on different reflex measures.

Various anatomical and physiological factors which may influence reflex sensitivity are indicated, and the need to analyse these factors is stressed, especially in the context of those theories which postulate a general factor of conditionability.     

Examining culturally based variables associated with ethnicity: influences on credibility perceptions of empirically supported interventions

Treatment rationales for 2 widely used and empirically supported interventions, cognitive therapy (CT) and time-limited dynamic psychotherapy (TLDP), were examined for their perceived credibility among 136 Asian American college students. This study conducted a comprehensive analysis of culturally based variables (often assumed to underlie ethnicity) and their related effects on credibility perceptions. Variables assessed included cultural identity, self-construals, values, and mental health beliefs. Participants were randomly assigned to read either a CT or TLDP treatment rationale for depression and then rated the credibility of the interventions. Results indicated that cultural identity and self-construals moderated credibility ratings across CT and TLDP rationales. Findings underscore the importance of moving beyond ethnic group analyses to the examination of specific culturally based variables.     

It's about timing and change: pubertal transition effects on symptoms of major depression among African American youths

Effects of early physical maturation and accelerated pubertal changes on symptoms of major depression were examined in 639 African American children. Three rival hypotheses, early timing, off-time, and stressful change, were tested using 2 waves of data (mean ages = 11 and 13 years). The pubertal effect operates differently according to children's gender and age. For girls, early maturation was consistently associated with elevated levels of depressive symptoms. For boys, early maturers manifested elevated levels of depression only at age 11, but these symptoms subsided by age 13. Boys who experienced accelerated pubertal growth over time displayed elevated symptom levels. Results support the early timing hypothesis for girls and the stressful change hypothesis for boys. Time at assessment is critical when examining boys' pubertal transition.     

The automaticity of race and Afrocentric facial features in social judgments

Four experiments were conducted to examine the automaticity of stereotyping based on racial category and (within-race) Afrocentric facial features. Results showed that both forms of stereotyping are efficient processes, able to operate when cognitive resources are highly restricted. The 2 differed, however, in their controllability. Participants demonstrated that they were sensitized to race-based stereotypes and able to control that influence to a significant degree. In contrast, participants appeared to be largely unaware of using Afrocentric features to make stereotypic inferences, and they proved unable to avoid doing so, even when they were given explicit information about the process and they demonstrated that they could easily and reliably identify the relevant features.     

Brand (in)fidelity: When Flirting with the Competition Strengthens Brand Relationships

We document the existence and consequences of brand flirting: a short‐lived experience in which a consumer engages with and/or indulges in the alluring qualities of a brand without committing to it. We propose that brand flirting is exciting, and that when consumers flirt with a brand other than their typically preferred brand in the same product category, they can transfer this excitement to their preferred brand—resulting in even greater love and desire for it. Consistent with this conceptual account, we demonstrate that this brand flirting effect is mediated by excitement. Moreover, the brand flirting effect is most likely to emerge under conditions that facilitate arousal transfer: when consumers are highly committed to their preferred brand, and when the brand with which consumers flirt is similar to their preferred brand.     

Participatory work place intervention for stress prevention in primary health care. A randomized controlled trial

The aim of this study is to explore whether a participatory, organizational intervention can reduce work-related risk factors, and thereby prevent stress-related ill health. We build on the job demand-control and effort-reward imbalance models of stress. It is a two-armed randomized trial, with one primary health care unit receiving the intervention and a two-unit control group. Validated questionnaires for the assessment of psychosocial work environment and health were administered, at the baseline and at 6 and 12-month follow up. The primary outcome was job strain. Secondary outcomes were effort–reward imbalance, exhaustion, sleep, and recovery. Group-level objective data on workload and data about relevant processes during the study were continuously collected. The changes in the intervention group with regard to job strain, effort-reward imbalance, exhaustion, sleep and recovery were not statistically different from changes in the control group. For the non-exhausted employees though, reward was significantly higher at follow up compared to baseline, but only in the intervention group. An important piece of information is that the objective workload was statistically significantly higher in the intervention group throughout the study. Not all the components of the intervention were implemented as intended. Context and process information, such as objective data and implementation fidelity are necessary for a valid interpretation of the results.     

The roles of chronological age and time perspective in memory positivity

The observation that older adults show enhanced cognition for emotionally positive information has been labeled the positivity effect (Reed, Chan, & Mikels, 2014). According to the Socioemotional Selectivity Theory (SST, Carstensen, 1991), a prominent lifespan development theory, cognition is strongly influenced by motivational goals, and these goals are impacted by subjective time perspective. Although the positivity effect is most commonly observed in older adults, as age usually co-varies with time perspective, the SST posits that time perspective, not age, is the key explanatory factor of positivity. We examined the effects of these predictors on positivity in an episodic memory task in younger and older adults and found that age, not time perspective, was a key predictor of memory positivity. Our results add to the growing literature that challenge the notion that time perspective is the driving force behind age-related differences in emotional processing and functioning.     

Prayer Coping,Disclosure of Trauma,and Mental Health Symptoms Among Recently Deployed United States Veterans of the Iraq and Afghanistan Conflicts

U.S. military veterans of the Iraq and Afghanistan conflicts are at risk for developing adverse mental health symptoms. This study was conducted to examine the associations between prayer coping, attitudes toward trauma disclosure, and mental health symptoms (posttraumatic stress disorder [PTSD] and depression) among 110 U.S. veterans who had returned from deployments in Operation Enduring Freedom and Operation Iraqi Freedom within the previous 6 months. Bivariate analyses revealed that prayer coping was positively correlated with an urge to talk about potentially traumatic experiences. When controlling for combat exposure, social support, and disclosure attitudes, multivariate regression analyses indicated that two of the prayer functions—praying for assistance and for calm and focus—were each uniquely linked with less PTSD and depressive symptomatology. In addition, a reliance on avoidant prayer was uniquely correlated with greater depressive symptomatology. These findings support emerging ideas about prayer as a form of trauma disclosure and highlight the relevance of this approach to coping for veterans as they readjust to civilian life.     

Newborns’ attention is driven by the translational movement

The present study investigated whether 2-day-old newborns are able to discriminate two translating meaningless Point-Light Displays (PLD) videos, in which the shape of one of them changes compared to that of the other along the trajectory, independently from movement kinematics, and if this ability is present both when stimuli differed at the end or at the beginning of the movement. To manipulate the instant in which along the movement the difference between stimuli was evident, and to maintain every unspecific dissimilarity possibly determining the preference, videos were played in a loop either forward or backwards. In Experiment 1, PLD stimuli moved with natural accelerated-decelerated kinematics; in Experiment 2 they moved at constant velocity. Four groups of newborns were submitted to the preferential looking technique experiments. Results showed that newborns looked longer at natural kinematics and that, irrespective of the type of kinematics, they discriminated the two stimuli only when videos were played forward, that is, only when stimuli differed at the end of the movement. These data suggest that, independently from kinematics, movement translational components induce newborns to allocate attention at the end of the observed movement. Given the strict link between attention and eye movements, we suggest that this effect may bootstrap the system and give rise to proactive gaze, the typical gaze behaviour present during executed and observed goal-directed actions.     

Incarcerated Violent Offenders' Ability to Avoid Revealing Their Potential for Violence on the Rorschach and the MMPI–2

Recently, Hartmann and Hartmann (2014) Hartmann, E., &; Hartmann, T. (2014): The impact of exposure to Internet-based information about the Rorschach and the MMPI–2 on psychiatric outpatients' ability to simulate mentally healthy test performance, Journal of Personality Assessment, 96, 432–444. doi:10.1080/00223891.2014.882342.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar] found that psychiatric outpatients, both with and without access to Internet-based information about the Rorschach Inkblot Method (RIM; Weiner, 2003 Weiner, I. B. (2003). Principles of Rorschach interpretations (2nd ed.). Mahwah, NJ: Erlbaum. [Google Scholar]) and the MMPI–2 (Butcher, Dahlstrom, Graham, Tellegen, &; Kaemmer, 1989 Butcher, J. N., Dahlstrom, W. G., Graham, J. R., Tellegen, A., &; Kaemmer, B. (1989). Manual for the Restandardized Minnesota Multiphasic Personality Inventory: MMPI–2. An administration and interpretive guide. Minneapolis: University of Minnesota Press. [Google Scholar]), were unable to imitate healthy test performance on these tests. We replicated the study by administering the RIM and the MMPI–2 to 63 incarcerated violent offenders using similar testing conditions. As in the previous study, comparisons were made not only among the 3 subgroups of incarcerated offenders, but also between these offender groups and the group of nonpatients examined in the previous study. On the RIM, Internet-coached and uncoached “faking good” offenders produced records with significantly higher F% and X–% and significantly lower M, m, SumC, X+%, P, AG, and COP than nonoffenders under standard instructions (effect sizes between d = 0.24 and d = 2.39). For AgC, AgPot, AgPast, and TCI% there were no significant differences between the faking offenders and the nonoffenders under standard instructions. On the MMPI–2 clinical scales, there were no significant differences between the faking good groups and the nonoffenders under standard instructions, except on Hs, Pd, and Sc. Both faking groups were identifiable by their high L scale scores. Although both faking groups managed to avoid giving responses with aggressive and generally psychopathological content on the RIM, they were unable to produce test profiles demonstrating healthy test performance on any of the tests; nevertheless, Internet-based test information might weaken test validity.
