Contribution of the parafascicular nucleus in the spontaneous object recognition task

The parafascicular (PF) nucleus, a posterior component of the intralaminar nuclei of the thalamus, is considered to be an essential structure in the feedback systems of basal ganglia–thalamo-cortical circuits critically involved in cognitive processes. The specific role played by multimodal information encoded in PF neurons in learning and memory processes is still unclear. We conducted two experiments to investigate the role of the PF in the spontaneous object recognition (SOR) task. The behavioral effects of pretraining rats with bilateral lesions of PF with N-methyl-D-aspartate (NMDA) were compared to vehicle controls. In the first experiment, rats were tested on their ability to remember the association immediately after training trials and in the second experiment after a 24 h delay. Our findings provide evidence that PF lesions critically affect both SOR tests and support its role in that non-spatial form of relational memory.     

The association between valuing popularity and relational aggression: the moderating effects of actual popularity and physiological reactivity to exclusion

The association between having a reputation for valuing popularity and relational aggression was assessed in a sample of 126 female children and adolescents (mean age = 12.43 years) at a 54-day residential summer camp for girls. Having a reputation for valuing popularity was positively related to relational aggression. This association was moderated by both popularity and physiological reactivity to social exclusion (i.e., respiratory sinus arrhythmia reactivity [RSAR] and heart rate reactivity [HRR]). Popular girls with a reputation for valuing popularity were at greater risk for engaging in relational aggression when they also exhibited blunted reactivity to social exclusion. Conversely, girls who had a reputation for valuing popularity but were not popular (i.e., the “wannabes”) were at risk for engaging in relational aggression when they exhibited heightened reactivity to exclusion.     

Mechanisms of resurgence II: Response-contingent reinforcers can reinstate a second extinguished behavior

Three experiments with rat subjects examined resurgence of an extinguished instrumental response using the procedure introduced by Epstein (1983) with pigeons. There were three phases: (1) initial acquisition of pressing on a lever (L1) for pellet reward, (2) extinction of L1, and (3) a test session in which a second lever (L2) was inserted, briefly reinforced, and then extinguished. Experiment 1 confirmed that if pressing L2 delivered 20 pellets followed by extinction, rats would resume L1 responding in the final test. Experiment 2 compared the effects of response-contingent and non-contingent rewards delivered upon insertion of L2. Although insertion of L2 alone did not increase L1 responding, response-contingent and non-contingent rewards led to comparable increases in L1 responding. Experiment 3 found that the delivery of non-contingent pellets during extinction of L1, which would be expected to reduce the ability of pellets to set the occasion for the L1 response, also reduced the effects of both response-contingent and non-contingent rewards during the final test. The results indicate that in this method, the resurgence treatment leads to an increase in L1 pressing due to simple presentation of the pellet; delivering the reinforcer after extinction of L1 reinstates L1 responding by setting the occasion for the L1 response.     

A functional perspective on group memberships: Differential need fulfillment in a group typology

The social motivation functions of intimacy, task, and social category groups were investigated. In two studies, participants were asked to consider the extent to which their group memberships fulfilled several needs. A factor analysis confirmed that the needs comprised three factors: affiliation, achievement, and identity. Intimacy groups were associated with affiliation needs, task groups were associated with achievement needs, and social category groups were associated with identity. A study using implicit measures reinforced those results, revealing the presence of the same implicit associations between group types and need fulfillments. A final study manipulated participants’ need state through a priming procedure. Priming a specific need (affiliation, achievement, and identity) led to an increased accessibility of the group type that was best suited to meet that need (intimacy, task, social category, respectively). Results help clarify the functional aspects of groups and have implications for the perception and organization of group-level information.

A relational account of intellectual autonomy

According to relational views of autonomy, some social relations or forms of dependence are necessary for autonomous agency. Recent relational theorists have primarily focused on autonomy of action or practical autonomy, and the result has been a shift away from individualistic conceptions of autonomy in the practical realm. Despite these trends, individualistic conceptions are still the default when it comes to autonomy of belief or intellectual autonomy. In this paper, I argue for a relational account of intellectual autonomy. Specifically, I claim that intellectual autonomy requires a sense of one’s standing as an equal member of the epistemic community.     

An outcome evaluation of Functional Family Therapy for court‐involved youth

This article presents results of a study on the effectiveness of Functional Family Therapy (FFT), a family intervention designed to prevent delinquency. The sample includes 155 court‐involved youth. This study employs two complementary outcomes: court‐obtained data on recidivism and the clinical data on clients’ psychosocial functioning, the Strengths and Needs Assessment (SNA). Adolescents in the treatment and in the comparison groups experienced statistically significant improvements on the majority of the SNA domains. Although youths in the treatment group improved more, the differences between the groups were not statistically significant. Multivariate analysis showed that youths in FFT had significantly lower odds of recidivism as measured by reconvictions for drug offenses, property offenses and technical violations. The results suggest that FFT was effective in reducing recidivism, however, such reductions cannot be attributed to improvements in the SNA scores.     

ICD-11 guidelines for psychotic,mood, anxiety and stress-related disorders in Mexico: Clinical utility and reliability

Background/Objective: The World Health Organization's diagnostic guidelines for ICD-11 mental and behavioural disorders must be tested in clinical settings around the world to ensure that they are clinically useful and genuinely global. The objective is evaluate the inter-rater reliability and clinical utility of ICD-11 guidelines for psychotic, mood, anxiety- and stress-related disorders in Mexican patients. Method: Adult volunteers exhibiting the selected symptoms were referred from the pre-consultation unit of a public psychiatric hospital to an interview by a pair of clinicians, who subsequently assigned independent diagnoses and evaluated the clinical utility of the diagnostic guidelines as applied to each particular case, on the basis of a scale developed for this purpose. Results: 23 clinicians evaluated 153 patients. Kappa scores were strong for psychotic disorders (.83), moderate for stress-related (.77) and mood disorders (.60) and week for anxiety and fear-related disorders (.43). A high proportion of clinicians considered all diagnostic guidelines to be quite to extremely useful as applied to their patients. Conclusions: ICD-11 guidelines for psychotic, stress-related and mood disorders allow adequate inter-rater consistency among Mexican clinicians, who also considered them as clinical useful tools.     

Exploration of virtual mazes by rhesus monkeys (<Emphasis Type="Italic">Macaca mulatta</Emphasis>)

A chasm divides the huge corpus of maze studies found in the literature, with animals tested in mazes on the one side and humans tested with mazes on the other. Advances in technology and software have made possible the production and use of virtual mazes, which allow humans to navigate computerized environments and thus for humans and nonhuman animals to be tested in comparable spatial domains. In the present experiment, this comparability is extended even further by examining whether rhesus monkeys (Macaca mulatta) can learn to explore virtual mazes. Four male macaques were trained to manipulate a joystick so as to move through a virtual environment and to locate a computer-generated target. The animals succeeded in learning this task, and located the target even when it was located in novel alleys. The search pattern within the maze for these animals resembled the pattern of maze navigation observed for monkeys that were tested on more traditional two-dimensional computerized mazes.     

Relational operants: processes and implications: a response to Palmer's review of Relational Frame Theory

Palmer has recently criticized Relational Frame Theory (RFT) on the grounds that it has developed data in search of a principle. In this reply, we show that he has done so by attacking fundamental concepts within behavior analysis itself, including the functional nature of an operant and contingencies of reinforcement as a behavioral process. His claim that RFT appeals to new behavioral principles to explain the development of relational operants is shown to be incorrect: As with any operant, RFT appeals to a history of contacted consistencies in contingencies across multiple ex-emplars to explain them. New principles only emerge later as a logically necessary extension of such operants if they exist--a view that Palmer failed to address or appreciate. Palmer's desire to see the use of methods other than matching-to-sample is proper but already largely satisfied in the empirical literature on RFT. We show Palmer's defense of Skinner's definition of verbal behavior to be illogical and unresponsive to the empirical challenge behavior analysis faces. Palmer's alternative common sense mediational associationistic account is another in more than a century of such accounts, all of which have failed empirically. At its root, Palmer's criticism is based on a mechanistic philosophy that is hostile to a traditional functional behavior analytic approach.
