Enhanced Implicit Sequence Learning in College‐age Video Game Players and Musicians

We examined whether college‐age video game players and musicians are better than controls at implicit sequence learning in the Alternating Serial Reaction Time Task. People learn to use subtle sequence regularities to respond more accurately and quickly to predictable versus non‐predictable events. Although previous studies have shown experts' enhanced processing speed and perception, this is the first to demonstrate that people who regularly play video games or a musical instrument showed greater implicit sequence learning, suggesting that experience playing games or music may improve the efficiency with which people learn sequential regularities in the environment.

The "what" and the "how" of dispositional mindfulness: using interactions among subscales of the five-facet mindfulness questionnaire to understand its relation to substance use

Although self-report measures of dispositional mindfulness have good psychometric properties, a few studies have shown unexpected positive correlations between substance use and mindfulness scales measuring observation of present-moment experience. The current study tested the hypothesis that the relationship between present-moment observation and substance use is moderated by the tendency to be nonjudgmental and nonreactive toward the observed stimuli. Two hundred and ninety-six undergraduates completed the five-facet mindfulness questionnaire (FFMQ), a calendar measuring periods of substance use, and a measure of the five-factor model of personality. Controlling for FFMQ and personality subscales, significant interactions between the observing and nonreactivity subscales indicated that the observing subscale was negatively associated with substance use at higher levels of nonreactivity but positively associated with periods of substance use at lower levels of nonreactivity. Results support the use of statistical interactions among FFMQ subscales to test for the presence of interactive effects of different aspects of mindfulness.     

The methods of reflexivity

Abstract

This paper will explore different uses of the term reflexivity in qualitative research. After discussing the foundational role of phenomenology and hermeneutics in the practices of reflexivity, this paper will present four methodological approaches to reflexivity. Distinctions will be made between personal reflexivity, interpersonal reflexivity, methodological reflexivity, and contextual reflexivity, and examples of research from each perspective will be presented. It will be argued that integration of these perspectives is possible thanks to their common foundation in phenomenology and henneneutics, and an example of such integration in practice will be provided.     

Appraisals of Fear, Helplessness, and Perceived Life-Threat During Emergent Cardiac Surgery: Relationship to Pre-surgical Depression, Trauma History, and Posttraumatic Stress

Depression and posttraumatic stress (PTS) have been linked to medical/psychological outcomes following coronary artery bypass graft (CABG) surgery. This study assessed pre-surgical trauma history, PTS, and depression; and peri-surgical appraisals of fear, helplessness, and perceived life-threat among 110 patients. All CABGs were emergent, rather than elective, surgeries. In hierarchical multiple regressions, total severity score for pre-surgical PTS predicted fear regarding the cardiac event and the CABG, and perceived life-threat regarding the cardiac event and the CABG. Pre-surgical depression predicted perceived helplessness regarding the cardiac event and the CABG, and contributed to prediction of perceived life-threat. Trauma history contributed to prediction of fear and perceived helplessness regarding surgery (but not regarding the cardiac event necessitating surgery). When posttraumatic stress disorder diagnosis (PTSD) was entered, rather than total severity of PTS, PTSD did not predict any appraisals, and depression showed stronger prediction of fear, helplessness, and perceived life-threat than did PTSD.     

The logic sense: exploring the role of executive functioning in belief and logic-based judgments

Abstract

The Default Interventionist account suggests that by default, we often generate belief-based responses when reasoning and find it difficult to draw the logical inference. Recent research, however, shows that in some instances belief judgments take longer, are more prone to error and are more affected by cognitive load. One interpretation is that some logical inferences are available automatically and require intervention in order to respond according to beliefs. In two experiments, we investigate the effortful nature of belief judgments and the automaticity of logical inferences by increasing the inhibitory demands of the task. Participants were instructed to judge conclusion validity, believability and either font colour or font style, to increase the number of competing responses. Results showed that conflict more strongly affects judgments of believability than validity and when inhibitory demands are increased, the validity of an argument impacts more on belief judgments. These findings align with the new Parallel Processing model of belief bias.     

Event Timing and Age Deficits in Higher-Order Sequence Learning

ABSTRACT

Recent studies have reported age deficits in learning sequences that contain subtle sequential regularities [e.g., Curran (1997) Curran, T. 1997. Effects of aging on implicit sequence learning: Accounting for sequence structure and explicit knowledge. Psychological Research, 60(1–2): 24–41.  [Google Scholar] Psychological Research, 60(1–2), 24; D. V. Howard et al. (2004) Howard, D. V., Howard, J. H. Jr, Japikse, K., DiYanni, C., Thompson, A. and Somberg, R. 2004. Implicit sequence learning: Effects of level of structure, adult age, and extended practice. Psychology and Aging, 19(1): 79–92. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar] Psychology and Aging, 19(1), 79; Howard, J. H. Jr, & Howard, D. V. (1997) Howard, J. H. Jr and Howard, D. V. 1997. Age differences in implicit learning of higher order dependencies in serial patterns. Psychololgy and Aging, 12(4): 634–656. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]. Psychololgy and Aging, 12(4), 634]. This finding is of potential theoretical interest, but the contribution of sequence event timing to this deficit has not been investigated. This study used an alternating serial reaction time task to examine implicit sequence learning in young adults when event timing mimicked that experienced by older adults in previous research. We varied the response-to-stimulus interval directly in Experiment 1 and indirectly by degrading the stimuli to influence response time in Experiment 2. Results indicate that these “aged” young adults learned the higher-order sequence structure implicitly, but they learned less than young controls and more than old adults on some measures of implicit learning in both experiments. In addition, these two different experimental manipulations produced distinct patterns of deficits despite having nearly identical effects on event sequence timing. These findings suggest that event timing alone cannot explain the age deficits observed in high-order implicit sequence learning.     

Color Preference and Food Choice Among Children

The effects of color on children's food choices were investigated. Subjects were 120 children who were equally distributed among each of the combinations of age (5 vs. 9 years old), sex (male vs. female), food type (3 types of candies), and color (red, green, yellow, and orange) in a counterbalanced, factorial, analysis-of-variance design with repeated measures on subjects. A significant main effect for color indicated that children preferred foods that were red, green, orange, and yellow, in that order. Interpretation of this main effect was not interfered with by main effects or interaction terms involving age, sex, or food type, which served as alternative rival hypotheses.     

Enfleshing semiotics: The indexical and symbolic sign-functions

This essay engages the work of Robert Yelle in his text Semiotics of Religion: Signs of the Sacred in History. The author examines in particular his theorizing of the indexical sign function and its capacity to ‘enflesh’ the symbol. In the Peircean and Saussurean frames the symbol is an abstraction, a concept, and removed from the experiential. However, with the deployment of the indexical sign, as Yelle argues, the symbol is enfleshed and made experiential. Yelle's development of Peircean semiotics should prove to be very productive in the study of systems of belief and practice.
