Recollection deficits in dysphoric mood: An effect of schematic models and executive mode?

Depression and dysphoric mood states are often accompanied by quantitative or qualitative shifts in performance across a range of retention tasks. This study focuses on the recollection of both autobiographical events and word lists in dysphoric states. Recollection occurs when people are aware of some contextual detail allied to the encoding experience. This study establishes the presence of a recollection deficit in dysphoria in two distinct paradigms. In both autobiographical recall and in recognition memory, recollection in a dysphoric group was at lower levels than recollection in matched controls. The study examines the hypothesis that the extent of recollection is influenced by two factors: (1) the degree of differentiation of schematic mental models; and (2) the executive mode that predominates when memory tasks are carried out, with the latter assumed to be altered by rumination. The relationship between responses based on recollection and alternative mnemonic responses could be predicted by measures of these two factors. The results are discussed in terms of the Interacting Cognitive Subsystems model (Teasdale & Barnard, 1993) and the perspective it offers on the relationship between meaning systems and executive functions (Barnard, 1999).     

Barriers and Supports to Substance Abuse Service Use Among Homeless Adults

Although there is a great need for substance abuse services among the homeless, many homeless individuals do not use those services. This study examined barriers and supports related to service use. Participants recognized a need for treatment and significant barriers to accessing care.     

The Relationship Between Defenses and Symptoms in Adolescent Psychopathology

The relationship between defense mechanisms and symptoms was assessed in a group of 196 psychiatrically hospitalized adolescents. Defense mechanisms were measured through the use of the Defense Mechanisms inventory (DMI); symptoms and problem behaviors were measured with the Youth Self-Report. Univariate and multivariate analyses indicated that externalizing symptoms are associated with defenses that locate the conflict outside of the self, whereas internalizing symptoms are associated with defenses that locate the conflict within the self. In contrast to previous reports, no gender differences, were found in defense preference, though gender differences were found in the relation of defenses to symptoms. The findings are consistent with clinical theory of defense processes and support the distinction between internalizing/externalizing behaviors and personality dimensions for both symptoms and defenses. The study supports the validity of the adolescent form of the DML.     

Toward an ethic of the biosphere

This article consists of three parts. The first explores the relation between paradox, de-paradoxication, and time, which I hold to be a relatively unattended yet very important tandem of concepts in Luhmann's work (Luhmann, 1993, 1995; Rasch, 2000). The second part will try to theoretically think through (de-paradoxicalize) a conundrum of present time: globalization and its opponents. In the third and last part, I briefly explore the paradox of conscious evolution, taking into account the specifics of the relations between social systems of communication and individual psychic systems in Luhmann's theory.     

Evolution and human choices

The postmodern world seems to have conclusively lost faith in the heady promises of human emancipation through rational understanding that have pervaded the Western world since the time of the Enlightenment. As the end of the millennium approaches and the evidence of man‐made environmental degradation accumulates nihilism and malaise color the future. This article argues that a clear understanding of both evolutionary forces and human consciousness permits to formulate a guardedly optimistic alternative view. It is advanced that the very sense of despair current circumstances have created may trigger a move toward a new form of psycho‐functional adaptation, simultaneously constituting a first instance of “conscious evolution” and fulfilling the progressive promise intrinsic in the full use of our rational faculties.     

Examining a negative halo effect to anabolic steroids users through perceived achievement goals,sportspersonship orientations,and aggressive tendencies

We investigated the social image of anabolic steroids (AS) users grounding our analysis on the achievement goal theory of Nicholls. Our main goal was to explore how an athlete’s acceptance of AS use would impact on the way that athlete will be perceived by others. Non‐AS‐using participants reacted to one of two scenarios portraying a male athlete either accepting or refusing to engage in drug use behavior. The results suggested that the acceptance of anabolic steroids yielded an unfavorable social image – perceivers inferred a predominant ego orientation to characterize the AS‐user’s motivation as well as weaker sportspersonship and a stronger proclivity for reactive aggression than instrumental aggression. Moreover, the analyses did not yield significant gender or interaction effects. Finally, those findings are commented in view of methodological shortcomings and of the perspectives that they may offer for future research concerning the motivational aspects of the social perceptions of drug use in sport.     

Personal values and prosocial behaviour in strategic interactions: Distinguishing value‐expressive from value‐ambivalent behaviours

Relying on the framework provided by Schwartz's theory of personal values, we investigated whether values can help explain prosocial behaviour. We first distinguished value‐expressive behaviours from value‐ambivalent behaviours. The former are compatible with primarily one value or with congruent values, the latter with mutually conflicting values. In Study 1, an analysis over all 41 (39 unpublished) samples in which we measured personal values and prosocial behaviour in monetarily incentivized strategic interactions (N = 1289; data collected between 2007 and 2010 in China, Finland, Germany, Israel, and the West Bank) supported our idea that personal values, universalism in particular, predict value‐expressive (prisoner's dilemma cooperation and trust game back‐transfers) but not value‐ambivalent behaviours (trust game transfers and ultimatum game proposals and responses). Study 2 (N = 56) focused on dictator game behaviours, which we expected and found to be strongly value‐expressive. The findings contribute to the ongoing discussion on whether and under which circumstances values shape behaviour. Copyright © 2013 John Wiley & Sons, Ltd.     

When do learners shift from habitual to agenda-based processes when selecting items for study?

Learners presumably attempt to allocate their study time to maximize reward, yet in some contexts, their study choices are driven by reading biases that would not maximize reward. For instance, when presented with items in a horizontal array that are worth different values if correctly recalled, learners will often first select the leftmost item (i.e., a reading bias), even when it is associated with the lowest value. In four experiments, we investigated the degrees to which various factors cause learners to shift to agenda-based regulation. On each trial, participants were presented with three cues and a point value (1, 3, or 5) for each. The participants could select any cue for study (in which case, its target would be presented) in any order. In Experiment 1, participants either selected items for study under time pressure or were given unlimited time to select items. Not limiting selection time increased the likelihood that higher-valued items would be prioritized for study, but reading biases still influenced item selection. In Experiment 2, participants could select only one item per trial, and higher-valued items were prioritized even more for study, but not exclusively so. In Experiments 3 and 4, we ruled out a lack of motivation and inaccurate task beliefs as explanations for why participants would sometimes choose lower-valued items. The results demonstrate the influence of a pervasive reading bias on learners’ item selections, but as importantly, they show that a shift toward agenda use occurs when habitual responding cannot maximize reward.
