Redundant food searches by capuchin monkeys (Cebus apella): a failure of metacognition?

This study investigated capuchin monkeys' understanding of their own visual search behavior as a means to gather information. Five monkeys were presented with three tubes that could be visually searched to determine the location of a bait. The bait's visibility was experimentally manipulated, and the monkeys' spontaneous visual searches before tube selection were analyzed. In Experiment 1, three monkeys selected the baited tube significantly above chance; however, the monkeys also searched transparent tubes. In Experiment 2, a bent tube in which food was never visible was introduced. When the bent tube was baited, the monkeys failed to deduce the bait location and responded randomly. They also continued to look into the bent tube despite not gaining any pertinent information from it. The capuchin monkeys' behavior contrasts with the efficient employment of visual search behavior reported in humans, apes and macaques. This difference is consistent with species-related variations in metacognitive abilities, although other explanations are also possible.     

The death of a mind: a study of Shakespeare's Richard III

Some of the most difficult aspects of our work involve our encounters with states of mind which are steeped in and spread violence. In these circumstances, we experience our best efforts to offer empathic presence and thought to avoid being assaulted and obliterated. In these instances, a figure from literature depicting the details in question may come to our aid. In the play popularly known as Richard III,William Shakespeare depicts how the state of mind which is etched by grievance and committed to revenge may impose the 'winter of (its) discontent' upon the sunny dispositions of others' healthy, integrated functioning. Shakespeare masterfully depicts Richard's cunning and malice, but he also illustrates how this vengeful state uses guile and 'changes of shape' to seduce its way past protective boundaries, utilizing the human qualities of trust, open-heartedness and longing as pathways for invasion, betrayal and emotional devastation. This paper will view excerpts of the play's text from a psychoanalytic perspective which suggests that several clear lessons about this obliterative state of mind may be gleaned: that grievance can only operate to spread grievance and destruction; that our open-hearted and trusting qualities do make us vulnerable to such invasion and betrayal, but that our humanity is also the only avenue for rescue from this plight. In addition a clear lesson is offered about the value of protected 'sanctuary', that is, mental space where our most potent tool in these circumstances, our discerning minds, might find residence.     

The impact of retrieval suppression on conceptual implicit memory

ABSTRACT

When people suppress retrieval of episodic memories, it can induce forgetting on later direct tests of memory for those events. Recent reports indicate that suppressing retrieval affects less conscious, unintentional retrieval of unwanted memories as well, at least on perceptually-oriented indirect tests. In the current study we examined how suppressing retrieval affects conceptual implicit memory for the suppressed content, using a category verification task. Participants studied cue-target words pairs in which the targets were exemplars of 22 semantic categories, such as vegetables or occupations. They then repeatedly retrieved or suppressed the targets in response to the cues for some of those pairs. Afterwards, they were exposed to the targets intermixed with novel items, one at a time, and asked to verify the membership of each of the words in a semantic category, as quickly as possible. Judgment response times to studied words were faster than to unstudied exemplars, reflecting repetition priming, as has been previously observed. Strikingly, the beneficial effects of prior exposure on response time were eliminated for targets that had been suppressed. Follow-up explicit memory tests also demonstrated that retrieval suppression continued to disrupt episodic recall for the items that had been just been re-exposed on the category verification test. These findings support the contention that the effects of retrieval suppression are not limited to episodic memory, but also affect indirect expressions of those memories on conceptually oriented tests, raising the possibility that underlying semantic representations of suppressed content are affected.     

Breaks are Better: A Tier II Social Behavior Intervention

Multi-tiered systems of social behavioral support in schools provide varying levels of intervention matched to student need. Tier I (primary or universal) systems are for all students and are designed to promote pro-social behavior. Tier III (tertiary or intensive) supports are for students who engage in serious challenging behavior that has not responded to other efforts. In between Tier I and Tier III are Tier II (secondary or targeted interventions), for students at risk for developing more serious problematic behavior. The purpose of this study was to evaluate Breaks are Better, a Tier II intervention designed for students who engage in problem behavior maintained by avoidance of instructional activities. Breaks are Better builds on an evidence-based Tier II intervention, Check-in/Check-out, but includes key components to enhance its effectiveness for students who avoid instruction. Working with three typically developing elementary school students, we documented changes in problem behavior during academic instruction following the implementation of Breaks are Better. Further, students and teachers rated the intervention as both feasible and valuable.     

Using Point-Of-View Video Modeling and Forward Chaining to Teach a Functional Self-Help Skill to a Child with Autism

This study examined the effectiveness of point-of-view video modeling in a forward-chaining procedure to teach a 4-year-old boy with autism to serve himself an afternoon snack. Task analysis was undertaken, and the task was divided into 3 phases with 1 video produced for each phase. A changing criterion design was used to evaluate the effects of the intervention on the participant’s ability to independently prepare and serve himself Weetbix. The results indicated that the combination of point-of-view modeling and forward chaining was effective in teaching the child to serve himself a snack without any prompting. The results also indicated that although the skill was maintained at follow-up, generalization to snacks other than Weetbix and to a different setting was limited. Parents reported satisfaction both with the procedures undertaken and with the outcomes of the intervention.     

Maintaining Order and Following the Rules: Gender Differences in Punishing Inmate Misconduct

For this article, we examine gender differences in how staff members address inmate misconduct. Using in-depth interviews with forty-three correctional employees, we focus on how their various disciplinary styles create interpersonal conflict between staff members. We find that over half of interviewees are identified as “formal responders” who consistently punish inmate misconduct with formal sanctions, even if doing so creates conflict within the organization. However, female formal responders also claim that they work closely with male inmates to explain the importance of following the rules. They state that this puts them at odds with their male co-workers who misinterpret this behavior as instigating sexual relationships.     

Role incongruency in marriage and family counseling

Abstract

Incongruency in role expectations produces strain in the marriage. But this doer not mean that spouses seeking marriage counseling experience more role incongruency than others. By studying 104 couples divided into experimental and control groups, it was found that there was no more. role expectation incongruency in the couples seeking marriage counseling than in those not seeking counseling. It might be that the major difference lies in how couples of both groups handle whatever incongruency may exist. What occurs between spouses can be easily applied to role incongruency among all members of the family.
