Dementia has a categorical, not dimensional, latent structure

Recently, Walters ("Dementia: Continuum or distinct entity?", Psychology and Aging, 2010, 25, 534-544) published a taxometric study suggesting a dimensional latent structure for the construct of dementia. However, because that study did not conceptualize dementia according to accepted conventions (i.e., there were no measures of cognitive change or independent functioning), its results may represent a false negative error caused by insufficient content coverage. We replicated Walters, and we used the same taxometric methods and the same data source-but with indicators of cognitive change and functional independence. Our results support a categorical interpretation of dementia; whereas Walters' results suggest that cognitive ability, rather than dementia, is dimensional in nature.

RESPONSE REPETITION AS AN ERROR‐CORRECTION PROCEDURE FOR ACQUISITION OF MATH FACTS AND MATH COMPUTATION

We used nonconcurrent and concurrent multiple baseline designs to evaluate the extent to which error correction with response repetition (RR) produced acquisition of math facts and correct math computation for four individuals diagnosed with intellectual disabilities. The results show that RR increased correct responding on (i) targeted math problems for three of four participants and (ii) math problems presented in alternative formats for two of two participants. The results are consistent with prior studies that used RR to increase correct sight‐word reading for individuals with intellectual disabilities. The findings are discussed in terms of how RR might be implemented in typical classroom settings. Copyright © 2011 John Wiley & Sons, Ltd.     

Selling and Sales Management in Action: Prospecting: A New Look at this Old Challenge

Prospecting is a fundamental step in the personal selling process. However, a wide variety of prospecting approaches exists among sales organizations and there is substantial disagreement in the terms used to describe prospecting elements and relationships. This article presents a working model that identifies and defines those elements and clearly demonstrates the strategic relationships among them. Insights and implications for managers are presented, along with suggestions for analyzing and modifying existing prospect-development programs.     

Reanalysis of Eysenck’s,Gray’s,and Zuckerman’s structural trait models based on a new measure: The Zuckerman–Kuhlman–Aluja Personality Questionnaire (ZKA-PQ)

The aim of this study was to explore the relationships of the dimensions and facets of the Zuckerman–Kuhlman–Aluja Personality Questionnaire (ZKA-PQ) with other psychobiological personality measures: the EPQ-RS (Eysenck Personality Questionnaire Revised, shortened version), I₇ (Impulsiveness Questionnaire) and SPSRQ-20 (Sensitivity to Punishment and Sensitivity to Reward Questionnaire, 20-item version). It is intended to test if findings reported with Zuckerman’s previous instrument (ZK-PQ) about the relationships between the three biologic-factorial personality models are replicated, giving evidence about the validity of the ZKA-PQ. The sample analyzed was of 584 subjects (50.3% men and 49.7% women) from the Spanish general population. Correlational and factor analysis supported the expected relationships between similar constructs assessed by the ZKA-PQ and the other questionnaires based on Eysenck’s and Gray’s personality theories. On the other hand, the inclusion of the facets from the ZKA-PQ improved the validity of the questionnaire. Findings were discussed in the framework of the biological personality models, emphasizing the contribution of the ZKA-PQ to the psychobiological personality research.     

The Protective Influence of Relationship Commitment on the Effects of Facebook Addiction on Marital Disaffection

Abstract

Previous research has suggested that Facebook use can lead to adverse romantic relationship outcomes due to interpersonal conflicts, interactions with potential romantic alternatives, and jealousy. However, these associations have been explored mainly with undergraduates, focusing primarily on conflict rather than emotional disengagement. The current study examined the associations between Facebook addiction and marital disaffection (e.g., loss of love, emotional disengagement) amongst 138 (95 females and 43 males) cohabiting married Facebook users residing in the United States. The results revealed that Facebook addiction and marital disaffection were positively related, even after controlling for relationship commitment. Additionally, greater relationship commitment weakened the association between Facebook addiction and marital disaffection. There are likely multiple explanations for the current findings; however, results suggest that higher levels of relationship commitment may protect spouses against the negative relationship outcomes associated with Facebook addiction. Future longitudinal work with couples is needed to clarify the directionality of the relationship between Facebook addiction and marital disaffection.     

Behavioural,affective, and physiological effects of negative and positive emotional exaggeration

Emotion regulation is essential for the production of socially appropriate affect and successful interpersonal functioning. The relative inability to modulate affect, known as "emotional dysregulation", is associated with many common mood disorders (such as major depressive disorder or bipolar spectrum disorders). Thus, understanding the physiological processes underlying emotional regulation is extremely important. This experiment was designed to explore the affective, behavioural, and physiological responses associated with a rarely studied emotion regulation technique--exaggeration. A total of 52 undergraduate participants watched a 2 minute video designed to elicit either feelings of amusement (positive affect) or disgust (negative affect). Physiological recordings--including skin conductance, interbeat interval (IBI), high frequency (HF) power spectrum of heart rate variability (HRV), and sympathovagal balance (LF/HF)--were recorded for the 2 minutes prior to, during, and after mood induction. As expected, persons asked to exaggerate their responses were rated as behaviourally showing increased arousal relative to individuals in the natural-watch condition. With regard to IBI, those in the exaggerate condition experienced significantly greater IBI reductions (increased heart rate) during reactivity and IBI increases during recovery relative to those in the natural-watch condition (who showed the opposite pattern of response). Moreover, persons in the exaggerate condition evidenced increased sympathovagal balance in response to the emotional videos relative to those in the natural-watch condition. Results generally support and extend previous research findings designed to assess the impact of response-focused affect modulation strategies. Suggestions for future research are presented.     

Depressive implicit associations and adults' reports of childhood abuse

Theory and research suggest that negative events in childhood (e.g., childhood abuse) may contribute to the development of a cognitive vulnerability to depression. A limitation of past research, however, is that the majority has focused on explicit cognitions (e.g., attributional style) and it remains unclear whether similar relations would be observed for more implicit measures of depressive cognitions. This study investigated the relation between young adults' reports of childhood abuse and their implicit depressive cognitions, as measured by the Implicit Association Test. As hypothesised, young adults reporting a history of childhood abuse exhibited stronger implicit associations for depression-relevant stimuli than did individuals with no abuse history. These results were maintained even after statistically controlling for the influence of current depressive symptom levels.     

On the Functional Role of Implicit Visual Memory for the Adaptive Deployment of Attention Across Scenes

Although very little visual information is explicitly retained across views, some continuity of processing is afforded by implicit visual memory traces of previous views. These memory traces interact with attentional mechanisms to guide eye movements, cognition, and action. Two different memory mechanisms are described here. First, the deployments of focal attention and eye movements are facilitated towards recently attended features and locations (priming of popout). Second, attention is guided by implicit memory traces of specific visual contexts experienced in the past (contextual cueing). Compared to the visual memory tapped by change blindness tasks, the implicit memory mechanisms of priming of popout and contextual cueing do not require conscious intervention and may exhibit greater memory capacity, longer durability, and higher discriminability. Thus, these implicit traces of past views guide attention and eye movements to allow for effective access (indexing) to a scene's details, hence providing context and continuity to ongoing interactions with the perceptual world.     

Perception of Maximum Reaching Height When the Means of Reaching Are No Longer in View

Previous research has shown that perception of maximum reaching height is relative to reaching ability even when the means of performing this behavior would bring about (future) changes in reaching ability. Two experiments investigate whether this continues to be the case even when the means of reaching are no longer in view. The results show perception of maximum reaching height reflects impending changes to reaching ability both when the means of performing the reaching task (and changing reaching ability) are present and when they are no longer in view. The results are discussed in the context of prospectivity, retrospectivity, and flexibility—3 fundamental hallmarks of goal-directed behavior.     

“Money Helps”: People who inject drugs and their perceptions of financial compensation and its ethical implications

This study documents how people who inject drugs (PWID) in rural Puerto Rico perceive payments for participating in HIV epidemiological studies. In-depth interviews were conducted among a subset (n = 40) of active PWID older than 18 years of age who had been previously enrolled in a much larger study (N = 360). Findings suggest that financial compensation was the main motivation for initially enrolling in the parent study. Then, as trust in the researchers developed, participants came to perceive compensation as part of a reciprocal exchange in which they assisted researchers by providing a trustful account of their experiences and researchers reciprocated with financial support.
