Visual attention and its intimate links to spatial cognition

It is almost universal to regard attention as the facility that permits an agent, human or machine, to give priority processing resources to relevant stimuli while ignoring the irrelevant. The reality of how this might manifest itself throughout all the forms of perceptual and cognitive processes possessed by humans, however, is not as clear. Here, we examine this reality with a broad perspective in order to highlight the myriad ways that attentional processes impact both perception and cognition. The paper concludes by showing two real-world problems that exhibit sufficient complexity to illustrate the ways in which attention and cognition connect. These then point to new avenues of research that might illuminate the overall cognitive architecture of spatial cognition.     

“It’s Really No Big Deal”: The Role of Social Supply Networks in Normalizing Use of Cannabis by Students at Canadian Universities

Cannabis (marijuana) has undergone a normalizing process as indicated by high use rates, social tolerance, and broader cultural acceptance of its use in many countries. Users also maintain access through extended friendship networks that facilitate the cultural diffusion of the practice. The social nature of supply is herein theorized in terms of Goffman’s understanding of activities that function to preserve a sense of normalcy as a collective achievement enabling predictable constructions of reality. Based on in-depth interviews with undergraduate students, we explore how social networks of supply—characterized by casual access, reciprocity, and sharing—contribute to shared meanings about using marijuana as an unremarkable or “normal” thing to do.     

The Power of Being Positive: The Relation Between Positive Self-Concept and job Performance

Most managers would probably agree that positivity is something they value in employees, yet selection research has virtually ignored the relation between employee positivity and job performance. This article suggests that a broad personality trait, labeled positive self-concept or core self-evaluations, is a potentially important personality trait in the prediction of job performance. Positive self-concept consists of four specific traits previously studied in isolation: self-esteem, generalized self-ef- ficacy, locus of control, and (low) neuroticism or emotional stability. Data analyzed from 12 samples revealed that these specific traits are strongly correlated and comprise a common factor. Drawing from four motivation theories, we argue that the principal reason positive self-concept is linked to job performance is because positive employees are more motivated to perform theirjobs. We also argue that, in some jobs, positive self-concept may be an ability factor. Finally, we discuss various implemen- tation issues involved in using positive self-concept in selection decisions. Overall, this article suggests that positive self-concept is a trait deserving of more attention in selection research and practice.     

Implicit memory for negative and positive social information in individuals with and without social anxiety

Studies of memory bias for threat-relevant information in individuals with social anxiety have produced mixed results. These discrepancies may be because investigators have studied different memory processes or have used different memory tasks. We employed a video clarity judgement task to investigate implicit (capacity-free, automatic, unconscious) memory and a recognition task to investigate explicit (effortful, strategic, conscious) memory for threat in socially anxious individuals and nonanxious controls. Implicit memory for "old" (i.e., seen before) videos was defined as rating "old" videos as more clear than "new" (i.e., never seen before) videos. We created brief video clips that involved an actor or actress approaching the camera and commenting on some aspect of the viewer's actions, physical appearance, or belongings. Twenty-four videos were positive (e.g., "I really like your shoes"), and 24 were negative (e.g., "That is a horrible haircut"). Results revealed that the video clarity test was an effective measure of implicit memory. Furthermore, socially anxious individuals showed a larger implicit memory index for negative videos than did nonanxious and dysphoric controls. No group differences emerged for implicit memory for positive videos. Similarly, groups did not differ in recognition of, or false alarms for, positive and negative videos. These results demonstrate the role of implicit memory in social anxiety implying that information about threat may be automatically primed in these individuals.     

Victims’ and Observers’ Reactions to Organizational Unfairness: The Role of Moral-Altruist Personality

Researchers are divided on the role of self-relevance in reactions to organizational unfairness: whether workers react similarly when the unfairness is directed at themselves or at others. We claim that the importance of self-relevance depends on moral-altruist personality (Honesty-Humility). In a vignette study, sensitivity to unfairness was weaker when the targets were coworkers rather than the participants, but only among those with low Honesty-Humility. In a field study, Honesty-Humility was associated with greater sensitivity to organizational fairness towards all workers but not to one's own treatment by the authority. Thus, morality-altruism mitigates the impact of self-relevance on attitudes following unfairness.     

Hypnosis: a twilight zone of the top-down variety Few have never heard of hypnosis but most know little about the potential of this mind-body regulation technique for advancing science

An early form of psychotherapy, hypnosis has been tarnished by a checkered history: stage shows, movies and cartoons that perpetuate specious myths; and individuals who unabashedly write 'hypnotist' on their business cards. Hypnosis is in the twilight zone alongside a few other mind-body exemplars. Although scientists are still unraveling how hypnosis works, little is mystical about this powerful top-down process, which is an important tool in the armamentarium of the cognitive scientist seeking to unlock topical conundrums.     

Children's low affective perspective-taking ability is associated with low self-initiated pro-sociality

Children's affective perspective-taking (APT) may provide a basis for efficient social interaction. The APT abilities of 83 children from 46 same-sex sibling pairs (ages 36 to 72 months, M = 52.8; SD = 12.6) were assessed through their reactions to affectively loaded story situations, and children whose APT ability (but not general cognitive abilities) was low relative to other children of their age were designated as Low-APT children. These children were not less pro-social when specific social cues or requests for pro-social behavior were given by experimenters. However, low APT may hinder children's ability to infer the need for pro-social action from relatively subtle social cues. Although 46.9% of nonlow APT children behaved pro-socially in at least two of three opportunities they were given to perform a self-initiated pro-social behavior, none of the children who were low on APT did.     

The demise of short-term memory revisited: empirical and computational investigations of recency effects

In the single-store model of memory, the enhanced recall for the last items in a free-recall task (i.e., the recency effect) is understood to reflect a general property of memory rather than a separate short-term store. This interpretation is supported by the finding of a long-term recency effect under conditions that eliminate the contribution from the short-term store. In this article, evidence is reviewed showing that recency effects in the short and long terms have different properties, and it is suggested that 2 memory components are needed to account for the recency effects: an episodic contextual system with changing context and an activation-based short-term memory buffer that drives the encoding of item-context associations. A neurocomputational model based on these 2 components is shown to account for previously observed dissociations and to make novel predictions, which are confirmed in a set of experiments.     

Training staff to conduct a paired-stimulus preference assessment

Three staff members were trained to conduct stimulus preference assessments using a paired-stimulus format with 8 children with autism. Staff were trained to mastery level using brief instruction, a video model, and rehearsal with verbal feedback. Training took about 80 min per staff member. Results demonstrated that staff rapidly learned to correctly perform paired-stimulus preference assessments with children.     

Posttraumatic stress disorder symptoms, psychological distress, personal resources, and quality of life in four groups of Holocaust child survivors

The objective of the present study was to inquire into the long-term effects of child survivors' Holocaust experience. To this end, 170 Holocaust survivors who were born after 1926 completed questionnaires with regard to psychological distress, Posttraumatic Stress Disorder (PTSD), Quality of Life (QoL), Self-identity, and Potency. The survivors were divided into four groups based on the setting of their experience during the Holocaust: Catholic Institutions, Christian foster families, concentration camps, and hiding in the woods and/or with partisans. Results showed that survivors who had been with foster families scored significantly higher on several of the measures of distress, whereas survivors who had been in the woods and/or with partisans scored significantly higher on several of the positive measures, QoL, potency, and self-identity. The discussion focuses on understanding the different experiences according to developmental theory and sense of control. It was concluded that there are group differences between child survivors according to their Holocaust experience.
