Effects of varying modality,surface features,and retention interval on priming in word-fragment completion

Subjects in Experiment i studied a list of words under varying presentation conditions (visual or auditory) and in two typographies within the visual condition (typed or hand printed) and then received a word-fragment completion test (e.g., —YS—E—Y formystery) in which the test cues also varied in typography. The main findings were that (1) priming occurred for all study items, relative to nonstudied items, but greater priming occurred for visual than for auditory presentation, and (2) performance in the visual conditions was better when typographies matched between study and test than when the typographies mismatched, but only for words studied in hand-printed form. These findings were generally replicated when the test was delayed 1 week, although priming declined across this retention interval (Experiment 2). In Experiment 3 subjects studied words that were either in focus or blurred and showed greater priming when test fragments were presented in the same manner as at study. Priming in the word-fragment completion task depends on matching surface characteristics of items between study and test and exemplifies the requirement of performing similar mental operations at study and test for maximizing performance (transfer-appropriate processing).     

Nobody Puts Baby in the Container: The Foetal Container Model at Work in Medicine and Commercial Surrogacy

This article argues that a particular metaphysical model permeates cultural practices surrounding pregnancy: the foetal container model. Widespread uncritical reliance on this view of pregnancy has been highly detrimental to women's liberty and reproductive autonomy. In this article, I extend existing critiques of the medical treatment of pregnant women to the context of the burgeoning commercial surrogacy industry. In doing so, I aim to show that our philosophical analysis in both spheres is constrained by the presupposition that the foetus and pregnant woman are metaphysically and ethically distinct entities. By exploring the similarities and differences between the expectations placed on pregnant women in these two spheres, I show that the foetal container model is not a homogeneous understanding of pregnancy applied consistently across contexts; rather, it has been used to justify various practices and attitudes toward pregnancy and pregnant women through different moral frameworks, in the service of different overarching aims.     

Gaze patterns during identity and emotion judgments in hearing adults and deaf users of American Sign Language

Deaf individuals rely on facial expressions for emotional, social, and linguistic cues. In order to test the hypothesis that specialized experience with faces can alter typically observed gaze patterns, twelve hearing adults and twelve deaf, early-users of American Sign Language judged the emotion and identity of expressive faces (including whole faces, and isolated top and bottom halves), while accuracy and fixations were recorded. Both groups recognized individuals more accurately from top than bottom halves, and emotional expressions from bottom than top halves. Hearing adults directed the majority of fixations to the top halves of faces in both tasks, but fixated the bottom half slightly more often when judging emotion than identity. In contrast, deaf adults often split fixations evenly between the top and bottom halves regardless of task demands. These results suggest that deaf adults have habitual fixation patterns that may maximize their ability to gather information from expressive faces.     

Training class inclusion responding in typically developing children and individuals with autism

In a class inclusion task, a child must respond to stimuli as being involved in two different though hierarchically related categories. This study used a Relational Frame Theory (RFT) paradigm to assess and train this ability in three typically developing preschoolers and three individuals with autism spectrum disorder, all of whom had failed class inclusion tests. For all subjects, relational training successfully established the target repertoire and subsequent testing demonstrated both maintenance and generalization. Limitations and future research directions are discussed.     

The Emotion Regulation Strategies of Adolescents and their Parents: An Experience Sampling Study

Parents are the main socialization agents in the development of emotion regulation (ER). In this study, we evaluated adolescents’ and their respective parents’ perspectives about their use of two ER strategies (cognitive reappraisal and expressive suppression) in daily life. In addition, we evaluated the within-family associations between adolescents’ and their parents’ use of strategies. We controlled for adolescents’ gender and age and the perceived quality of their relationships with their parents (mothers and fathers). The sample consisted of 33 12- to 18-year-old adolescent–father–mother triads, totaling 99 participants. Parents and adolescents reported their use of ER strategies in response to eight random prompts throughout the day, by means of the experience sampling method for 1 week. Participants provided 4082 reports on their momentary experiences. The data were analyzed using multilevel modeling to account for the hierarchical structure of the repeated daily assessments. The significant association between parents’ and adolescents’ use of ER strategies was specific to mother–adolescent dyads. The significant association between adolescents’ and their mothers’ ER strategies varied as a function of the adolescents’ age and the quality of their relationship with their mothers according to adolescents’ reports, but not as a function of adolescent gender. These findings suggest that mothers have a role in their adolescents’ emotion regulation in a developmental period characterized by autonomy from parental guidance.     

Emotional Intelligence Profiles in College Students and Their Fathers’ and Mothers’ Parenting Practices

The present study has two objectives: first, to analyze whether the dimensions that make up emotional intelligence (attention, clarity, and repair) give rise to different profiles of university students, and secondly, to determine whether these different profiles are differentially associated with the parenting practices that students report with regard to their fathers and mothers. Results obtained indicate the existence of different profiles of college students. The profile that corresponds to adequate emotional skills presents a lower score in attention, but higher scores in clarity, and especially in mood repair. The other two profiles are inadequate, in the first case because a higher score in emotional attention is accompanied by low scores in mood repair, and in the second case because low scores are presented in all three dimensions. Likewise, we verified the existence of significant differences in the educational practices of parents, the adequate profile is characterized by greater use of parenting dimensions considered to be positive, and at the same time, lower scores on dimensions considered to be negative. One of the dysfunctional profiles is associated with higher scores in positive practices, and is also associated with higher scores in practices considered to produce a negative effect. The second dysfunctional profile is associated with higher scores on the dimensions considered to be negative and lower scores on positive dimensions.     

Theory of mind and joint action in Parkinson’s disease

It has been suggested that the Theory of Mind (ToM) may rely on more basic processes of social cognition, such as action control (e.g., joint action), even if little is known about this relationship. The relationship between ToM and joint action can be studied in patients with Parkinson’s disease (PD), because they are characterized not only by a deficit in ToM (and in its cognitive and affective subcomponents) but also by a deficit in the inhibition of competing responses. Sixty PD patients and 60 matched healthy controls (HCs) performed a go/no-go Flanker task in both joint and individual conditions. Cognitive (Advanced Test or AT) and affective (Emotion Attribution Task or EAT) ToM also were measured. Thirty-five PD patients and matched HCs also performed the standard Flanker task, as a control measure. In patients, only individuals with high AT scores exhibited a joint Flanker effect, whereas in HCs the joint effect was found irrespectively of AT score. Patients with low EAT scores showed a greater interference effect than patients with high scores, whereas the opposite pattern was found for HCs. In regression analysis AT and EAT scores predicted the Flanker effect in the joint condition only. In the standard task, both groups showed a Flanker effect. The role of different fronto-striatal circuits, especially in PD patients, could explain the different involvement of cognitive and affective ToM in joint tasks. The Flanker effect is discussed considering the referential coding account and the attention-focus account as possible candidates to explain joint action effects.     

Dreaming and cognition in patients with frontotemporal dysfunction

Individuals with Parkinson’s disease (PD) and temporal lobe epilepsy (TLE) have hallucinations and mild cognitive dysfunction. The objective of this work was to study dreams in PD and TLE patients using a common functional model of dream production involving the limbic and paralimbic structures.Dreams were characterised in early-stage PD (19 males) and TLE patients (52) with dream diaries classified by the Hall van de Castle system and were compared with matched controls.In PD, there were significant differences between patients’ dreams and those of controls: animals, physical aggression, and a befriender were more common in patients, and aggressor and bodily misfortunes were less common. The dreams of patients with frontal dysfunction showed more aggressive features.TLE patients had lower recall than PD patients and a higher proportion of dreams involving family and familiar settings, lower proportions involving success, and a higher incidence of frontal dysfunction.The dreams of PD and TLE patients share important features.     

Hormonal regulation of delta opioid receptor immunoreactivity in interneurons and pyramidal cells in the rat hippocampus

Clinical and preclinical studies indicate that women and men differ in relapse vulnerability to drug-seeking behavior during abstinence periods. As relapse is frequently triggered by exposure of the recovered addict to objects previously associated with drug use and the formation of these associations requires memory systems engaged by the hippocampal formation (HF), studies exploring ovarian hormone modulation of hippocampal function are warranted. Previous studies revealed that ovarian steroids alter endogenous opioid peptide levels and trafficking of mu opioid receptors in the HF, suggesting cooperative interaction between opioids and estrogens in modulating hippocampal excitability. However, whether ovarian steroids affect the levels or trafficking of delta opioid receptors (DORs) in the HF is unknown. Here, hippocampal sections of adult male and normal cycling female Sprague-Dawley rats were processed for quantitative immunoperoxidase light microscopy and dual label fluorescence or immunoelectron microscopy using antisera directed against the DOR and neuropeptide Y (NPY). Consistent with previous studies in males, DOR-immunoreactivity (-ir) localized to select interneurons and principal cells in the female HF. In comparison to males, females, regardless of estrous cycle phase, show reduced DOR-ir in the granule cell layer of the dentate gyrus and proestrus (high estrogen) females, in particular, display reduced DOR-ir in the CA1 pyramidal cell layer. Ultrastructural analysis of DOR-labeled profiles in CA1 revealed that while females generally show fewer DORs in the distal apical dendrites of pyramidal cells, proestrus females, in particular, exhibit DOR internalization and trafficking towards the soma. Dual label studies revealed that DORs are found in NPY-labeled interneurons in the hilus, CA3, and CA1. While DOR colocalization frequency in NPY-labeled neuron somata was similar between animals in the hilus, proestrus females had fewer NPY-labeled neurons that co-labeled with DOR in stratum oriens of CA1 and CA3 when compared to males. Ultrastructural analysis of NPY-labeled axon terminals within stratum radiatum of CA1 revealed that NPY-labeled axon terminals contain DORs that are frequently found at or near the plasma membrane. As no differences were noted by sex or estrous cycle phase, DOR activation on NPY-labeled axon terminals would inhibit GABA release probability equally in males and females. Taken together, these findings suggest that ovarian steroids can impact hippocampal function through direct effects on DOR levels and trafficking in principal cells and broad indirect effects through reductions in DOR-ir in NPY-labeled interneurons, particularly in CA1.
