Effortful control,positive emotional expression,and behavior problems in children born preterm

The present study focused on the role of high effortful control in the expression of positive emotion and development of behavior problems in children born preterm (mean gestational age = 31.4 weeks). Using data from a prospective longitudinal study, the present study assessed effortful control and behavior problems at 24 and 36 months and positive emotional expression at 24 months in a sample of 173 children born preterm. Less positive emotional expression was associated with higher effortful control for boys but not girls. Higher effortful control was associated with fewer total behavior problems, but this relation was attenuated when socioeconomic assets were included in the model. More socioeconomic assets were associated with fewer behavior problems for both boys and girls and higher effortful control for girls. Socioeconomic assets appear to be an important factor in the development of effortful control and behavior problems in children born preterm regardless of gender, whereas positive emotional expression was important for boys. Future intervention research should examine fostering adaptive levels of effortful control in high-risk populations as a means to facilitate resilience processes.     

Concurrent and Longitudinal Relationships Between Development in Graphic,Language and Symbolic Play Domains from the Fourth to the Fifth Year

This research investigated the developing inter‐relationships between language, graphic symbolism and symbolic play both concurrently and longitudinally from the fourth to the fifth year of childhood. Sixty children (n = 60) aged between 3 and 4 years completed multiple assessments of language and assessments of graphic symbolism, symbolic play and non‐verbal intelligence. A year later, 31 children (n = 31) were re‐tested using the same assessments. The findings revealed that skills within each symbolic domain were inter‐related during the fourth year, appearing to develop in a domain‐general type fashion based upon a common underlying symbolic mechanism. However, between the fourth and the fifth years, only language had predictive validity, suggesting a shift towards the verbal mediation of symbolic play and graphic symbolism as language becomes progressively internalized (Vygotsky, 1962, 1978).

Learning Count Nouns and Adjectives: Understanding the Contributions of Lexical Form Class and Social-Pragmatic Cues

In two experiments, one hundred ninety-two 3-year-olds, 4-year-olds, and adults heard a novel word for a target object and then were asked to extend the label to one of two test objects, one matching in shape-based object category (the shape match) and the other matching in a property other than shape (the property match). We independently manipulated the lexical form class cues (count noun, adjective) and social-pragmatic cues (point actions, property-highlighting actions) accompanying the label. The impact of these two types of cue on extension differed markedly across age groups. Adults and 4-year-olds extended the word to the property match significantly more often when the term was modeled as an adjective and when it was presented with property-highlighting actions; but adults extended both adjectives and count nouns systematically to the property match when the speaker highlighted the non-shape property, whereas 4-year-olds systematically extended only adjectives to the property match under these conditions. Three-year-olds extended the word to the property match significantly more often when the label was modeled as an adjective but were not significantly affected by the social-pragmatic cues; and they failed to extend either adjectives or count nouns systematically to the property match when the speaker highlighted the non-shape property. We discuss the results in terms of the proposal that word learning draws on cues from multiple sources and the nature of the “shape bias” in lexical development.     

Propranolol and the Prevention of Post-Traumatic Stress Disorder: Is it Wrong to Erase the “Sting” of Bad Memories?

The National Institute of Mental Health (Bethesda, MD) reports that approximately 5.2 million Americans experience post-traumatic stress disorder (PTSD) each year. PTSD can be severely debilitating and diminish quality of life for patients and those who care for them. Studies have indicated that propranolol, a beta-blocker, reduces consolidation of emotional memory. When administered immediately after a psychic trauma, it is efficacious as a prophylactic for PTSD. Use of such memory-altering drugs raises important ethical concerns, including some futuristic dystopias put forth by the President's Council on Bioethics. We think that adequate informed consent should facilitate ethical research using propranolol and, if it proves efficacious, routine treatment. Clinical evidence from studies should certainly continue to evaluate realistic concerns about possible ill effects of diminishing memory. If memory-attenuating drugs prove effective, we believe that the most immediate social concern is the over-medicalization of bad memories, and its subsequent exploitation by the pharmaceutical industry.     

Perceptions of Humility: A Preliminary Study

Do people perceive humility as a strength or a weakness? The current study examined this question in a sample of 127 undergraduates. Contrary to common dictionary definitions of humility, which often emphasize its association with self-abasement, participants reported consistently positive views of humility. When recalling situations in which they felt humble, they typically reported success experiences associated with positive emotion. Participants clearly associated humility with good psychological adjustment, although they were less decisive about whether humility was associated with confidence or leadership. Although participants viewed humility as a strength across all social roles sampled, humility was viewed most favorably as a quality of religious seekers, less favorably as a quality of close others or subordinates, and least favorably as a quality of leaders or entertainers. Positive views of humility were associated with high self-esteem and religiosity. Less favorable views of humility were associated with narcissism—particularly its exploiting/entitled dimension.     

Discrimination of acoustically similar conspecific and heterospecific vocalizations by black-capped chickadees (<Emphasis Type="Italic">Poecile atricapillus</Emphasis>)

Chickadees produce a multi-note chick-a-dee call in multiple socially relevant contexts. One component of this call is the D note, which is a low-frequency and acoustically complex note with a harmonic-like structure. In the current study, we tested black-capped chickadees on a between-category operant discrimination task using vocalizations with acoustic structures similar to black-capped chickadee D notes, but produced by various songbird species, in order to examine the role that phylogenetic distance plays in acoustic perception of vocal signals. We assessed the extent to which discrimination performance was influenced by the phylogenetic relatedness among the species producing the vocalizations and by the phylogenetic relatedness between the subjects’ species (black-capped chickadees) and the vocalizers’ species. We also conducted a bioacoustic analysis and discriminant function analysis in order to examine the acoustic similarities among the discrimination stimuli. A previous study has shown that neural activation in black-capped chickadee auditory and perceptual brain regions is similar following the presentation of these vocalization categories. However, we found that chickadees had difficulty discriminating between forward and reversed black-capped chickadee D notes, a result that directly corresponded to the bioacoustic analysis indicating that these stimulus categories were acoustically similar. In addition, our results suggest that the discrimination between vocalizations produced by two parid species (chestnut-backed chickadees and tufted titmice) is perceptually difficult for black-capped chickadees, a finding that is likely in part because these vocalizations contain acoustic similarities. Overall, our results provide evidence that black-capped chickadees’ perceptual abilities are influenced by both phylogenetic relatedness and acoustic structure.     

Emergency Response Services Suicide: A Crisis in Canada?

This literature review sought to examine the extant literature on the relationship between emergency response services (ERS) personnel and suicide in Canada. The purpose was to determine what research has been conducted on suicide and suicide ideation among ERS, to contribute to knowledge in the area, and also to identify potential research gaps. Through a search of multiple databases (PubMed, Web of Science, Medline, Psyc Articles, Psyc Info, Science Direct, CINAHL) and additional hand searching, 40 articles were identified to meet search criteria and provide relevant information on this topic. The articles revealed that research has primarily focused on the traumatic stress and critical incidents encountered by emergency responders, while little research has been conducted specifically on suicide within these professions. The minimal research that has focused on suicide generally discusses ERS encounters with suicide victims and patients, rather than suicide in the context of their personal mental health. The limited research that does discuss ERS suicide is largely restricted to law enforcement and military personnel. Finally, the literature search identified a particular lack of research relevant to the Canadian context. A research agenda is recommended to further investigate suicide among ERS within Canada, and the impact these suicides have on colleagues, families and friends.     

Coping with transphobia in employment: Strategies used by transgender and gender-diverse people in the United States

Background: Transgender and gender-diverse (TGD) individuals face stigma in the general public and in the workplace. Research has suggested that TGD individuals may demonstrate unique coping strategies in the workplace in order to manage transphobia in that setting; however, further research is needed to identify the specific strategies that transgender individuals use to deal with transphobia at work.

Method: The present qualitative study utilized the grounded theory methodology to identify the specific coping strategies utilized to deal with transphobia at work. Participants included 45 TGD participants from the northeastern United States.

Results: The results of the study include the identification of eight coping-strategy themes including gender-presentation strategies, gender detachment, relationship navigating, resource utilization, job-performance strategies, maladaptive coping strategies, structural strategies, and power-acquisition strategies.

Conclusions: Implications of the present study suggest the resilience and diverse coping strategies that mental health providers can help TGD workers draw from in dealing with transphobia at work. In addition, there is a need for greater remediation and prevention of employment-related transphobia, including leadership within employment settings, greater legal protections, and enforcement of these laws in the United States.     

Object-location binding across a saccade: A retinotopic spatial congruency bias

Despite frequent eye movements that rapidly shift the locations of objects on our retinas, our visual system creates a stable perception of the world. To do this, it must convert eye-centered (retinotopic) input to world-centered (spatiotopic) percepts. Moreover, for successful behavior we must also incorporate information about object features/identities during this updating – a fundamental challenge that remains to be understood. Here we adapted a recent behavioral paradigm, the “spatial congruency bias,” to investigate object-location binding across an eye movement. In two initial baseline experiments, we showed that the spatial congruency bias was present for both gabor and face stimuli in addition to the object stimuli used in the original paradigm. Then, across three main experiments, we found the bias was preserved across an eye movement, but only in retinotopic coordinates: Subjects were more likely to perceive two stimuli as having the same features/identity when they were presented in the same retinotopic location. Strikingly, there was no evidence of location binding in the more ecologically relevant spatiotopic (world-centered) coordinates; the reference frame did not update to spatiotopic even at longer post-saccade delays, nor did it transition to spatiotopic with more complex stimuli (gabors, shapes, and faces all showed a retinotopic congruency bias). Our results suggest that object-location binding may be tied to retinotopic coordinates, and that it may need to be re-established following each eye movement rather than being automatically updated to spatiotopic coordinates.
