Look again: Phenomenology and mental imagery

This paper (1) sketches a phenomenological analysis of visual mental imagery; (2) applies this analysis to the mental imagery debate in cognitive science; (3) briefly sketches a neurophenomenological approach to mental imagery; and (4) compares the results of this discussion with Dennett’s heterophenomenology.     

The development of the Game Engagement Questionnaire: A measure of engagement in video game-playing

Deep engagement in video game-playing has the potential to be to be one important determinant of the impact of playing violent video games, but there are currently no reliable measures of this subjective experience. To fill this gap, the Game Engagement Questionnaire (GEQ) was developed using both classical and Rasch analyses. In Study 1 Rasch analyses provide support for the reliability and functionality of the GEQ scores. Rasch analyses also demonstrate that the GEQ has adequate separation, fit, rating scale functioning, and dimensionality, suggesting that one’s tendency to become engaged in video game-playing is a quantifiable construct. In Study 2, behavioral and questionnaire data supported the reliability and validity of the GEQ for predicting engagement in violent video games. The GEQ provides a psychometrically strong measure of levels of engagement specifically elicited while playing video games, and thus shows promise for future research examining risk and protective factors for negative game impact.     

Estimating the heritability of cognitive traits across dog breeds reveals highly heritable inhibitory control and communication factors

Animal Cognition - Trait heritability is necessary for evolution by both natural and artificial selection, yet we know little about the heritability of cognitive traits. Domestic dogs are a...     

Inviting the Significant Other of LGBT Clients into Substance Abuse Treatment Programs: Frequency and Impact

In the New York Metropolitan area, convenience samples of 194 LGBT and 107 heterosexual former clients of substance abuse programs were compared in regard to rate of invitation of their significant others into treatment for at least one session. No significant differences between sexual orientation groups were found. For LGBT respondents, inviting significant others into treatment resulted in improved program completion rates, greater satisfaction with treatment, enhanced feelings of counselor support, and higher abstinence rates at the end of treatment. For women, not having a significant other predicted higher abstinence rates at the end of treatment.     

Challenging the reliability and validity of cognitive measures: The case of the numerical distance effect

The numerical distance effect (NDE) is one of the most robust effects in the study of numerical cognition. However, the validity and reliability of distance effects across different formats and paradigms has not been assessed. Establishing whether the distance effect is both reliable and valid has important implications for the use of this paradigm to index the processing and representation of numerical magnitude in both behavioral and neuroimaging studies. In light of this, we examine the reliability and validity of frequently employed variants (and one new variant) of the numerical comparison task: two symbolic comparison variants and two nonsymbolic comparison variants. The results of two experiments demonstrate that measures of the NDE that use nonsymbolic stimuli are far more reliable than measures of the NDE that use symbolic stimuli. With respect to correlations between measures, we find evidence that the NDE that arises using symbolic stimuli is uncorrelated with the NDE that is elicited by using nonsymbolic stimuli. Results are discussed with respect to their implications for the use of the NDE as a metric of numerical processing and representation in research with both children and adults.     

Lessons in collaboration, four years post-Katrina

Four action researchers present a case study of a project conducted by members of a national family therapy organization and members of a local family therapy institute, which describes their efforts to collaborate with local disaster recovery workers 2 years after Hurricane Katrina. The aim of the collaboration was to create a local action research team to study best practices that strengthen resilience after disaster. The authors discuss choice points and dilemmas faced in finding collaborative partners and in clarifying what constitutes an invitation to work in a community. The case study illuminates tensions and understandings between outsiders and a community still facing the long-term effects of a disaster.     

Cortisol and symptoms of psychopathology in Russian and American college students

Cortisol is a key player in the hypothalamus-pituitary-adrenal (HPA) axis response to stress, and has been related to symptoms of depression and other stress-related pathology. The present study investigated the relationship between cortisol and survey measures of stress and psychopathology as well as lifestyle in Russian and American college students. Salivary cortisol was collected upon awakening, 30 min later, at 4 p.m., and at 10 p.m. by Russian and American college students. Survey measures of anxiety and depression, as measured by the Hopkins Symptom Checklist (HSCL-25) were collected as well as scores on the Trauma History Questionnaire (THQ). In addition, measures of drinking-related problems, as measured by the Alcohol Use Disorder Identification Test (AUDIT) and the "Cut down, Annoyed, Guilty, Eye-opener" (CAGE) were also completed. Consistent with the typically observed empirical pattern, cortisol levels increased in the 30 min after awakening and then declined across the day. Women reported more symptoms of anxiety than did men in both Russian and American samples. American students reported more symptoms of depression than did Russian students, though Russian students reported more traumatic life experiences. Americans had higher cortisol levels overall, though Russian students had larger changes in cortisol levels across the day, associated with both greater morning rises and afternoon declines in cortisol. While more Russian students reported smoking, American students reported more problems associated with alcohol use as measured by the AUDIT. The relationship between stress and health, mediating factors of lifestyle and coping, and the impact of social transition in Russia are discussed.     

Spatial attention modulates feature crosstalk in visual word processing

One major idea about spatial attention is that it serves to modulate crosstalk between features during reading. Two reading aloud experiments are reported in which a cue-validity manipulation was combined with manipulations that are thought to increase the likelihood of feature-level crosstalk: interletter spacing and the presence or absence of irrelevant features. Both experiments yielded an interaction between the effects of spatial cuing and each of these factors. These results are taken to support the hypothesis that when spatial attention is focused on the word, it provides protection against crosstalk among features in the context of reading aloud.
