The Relationship Between Nonsuicidal Self‐Injury and Suicidal Ideation

This correlational study was conducted with 403 undergraduate college students from 2 universities. The authors used path analysis and bootstrap regression to analyze the relationships between variables. Locus of control and family connectedness related to current nonsuicidal self‐injury (NSSI) engagement. However, when entered into the same regression, the variables current NSSI engagement and current NSSI number of methods used mediated all other relationships with suicidal ideation. Implications to current theories and clinical practice are provided.     

Areas of Interest as a Signal Detection Problem in Behavioral Eye‐Tracking Research

Decision researchers frequently analyze attention to individual objects to test hypotheses about underlying cognitive processes. Generally, fixations are assigned to objects using a method known as area of interest (AOI). Ideally, an AOI includes all fixations belonging to an object while fixations to other objects are excluded. Unfortunately, due to measurement inaccuracy and insufficient distance between objects, the distributions of fixations to objects may overlap, resulting in a signal detection problem. If the AOI is to include all fixations to an object, it will also likely include fixations belonging to other objects (false positives). In a survey, we find that many researchers report testing multiple AOI sizes when performing analyses, presumably trying to balance the proportion of true and false positive fixations. To test whether AOI size influences the measurement of object attention and conclusions drawn about cognitive processes, we reanalyze four published studies and conduct a fifth tailored to our purpose. We find that in studies in which we expected overlapping fixation distributions, analyses benefited from smaller AOI sizes (0° visual angle margin). In studies where we expected no overlap, analyses benefited from larger AOI sizes (>.5° visual angle margins). We conclude with a guideline for the use of AOIs in behavioral eye‐tracking research.

Benchmarking Treatment Response in Tourette’s Disorder: A Psychometric Evaluation and Signal Detection Analysis of the Parent Tic Questionnaire

This study assessed the psychometric properties of a parent-reported tic severity measure, the Parent Tic Questionnaire (PTQ), and used the scale to establish guidelines for delineating clinically significant tic treatment response. Participants were 126 children ages 9 to 17 who participated in a randomized controlled trial of Comprehensive Behavioral Intervention for Tics (CBIT). Tic severity was assessed using the Yale Global Tic Severity Scale (YGTSS), Hopkins Motor/Vocal Tic Scale (HMVTS) and PTQ; positive treatment response was defined by a score of 1 (very much improved) or 2 (much improved) on the Clinical Global Impressions – Improvement (CGI-I) scale. Cronbach’s alpha and intraclass correlations (ICC) assessed internal consistency and test-retest reliability, with correlations evaluating validity. Receiver- and Quality-Receiver Operating Characteristic analyses assessed the efficiency of percent and raw-reduction cutoffs associated with positive treatment response. The PTQ demonstrated good internal consistency (α = 0.80 to 0.86), excellent test-retest reliability (ICC = .84 to .89), good convergent validity with the YGTSS and HM/VTS, and good discriminant validity from hyperactive, obsessive-compulsive, and externalizing (i.e., aggression and rule-breaking) symptoms. A 55% reduction and 10-point decrease in PTQ Total score were optimal for defining positive treatment response. Findings help standardize tic assessment and provide clinicians with greater clarity in determining clinically meaningful tic symptom change during treatment.     

Studying Stepfamilies: Four Eras of Family Scholarship

Historically, there have always been stepfamilies, but until the early 1970s, they remained largely unnoticed by social scientists. Research interest in stepfamilies followed shortly after divorce became the primary precursor to stepfamily formation. Because stepfamilies are structurally diverse and much more complex than nuclear families, they have created considerable challenges for both researchers and clinicians. This article examines four eras of stepfamily scholarship, tracing the development of research questions, study designs and methods, and conceptual frameworks from the mid‐1970s to the present and drawing implications for the current state of the field.

Counterfactual intensity

Counterfactual intensity, the strength with which counterfactuals are experienced, influenced the magnitude of affective and preparative reactions. Intensity influenced reactions when counterfactual numbers were held constant for samples of participants' actual experiences (Study 1) and contributed significantly to responses over counterfactual numbers (Study 2) and reaction times (Study 3) after performing laboratory tasks. This was found when participants spontaneously generated counterfactuals (Study 2), and when participants responded to counterfactual statements (Study 3). As upward counterfactuals became intense, so did greater preparation and worse moods; as downward counterfactuals became intense, so did better moods and lesser preparation. Intense moods also conversely influenced the intensity of counterfactuals (Study 3). Conceptual and methodological implications and possibilities for future research are discussed.

Variable Perception of White Noise in Ambiguous Phonetic Contexts: The Case of /p/ and /f/

The roles of spectro-temporal coherence, lexical status, and word position in the perception of speech in acoustic signals containing a mixture of speech and nonspeech sounds were investigated. Stimuli consisted of nine (non)words in which either white noise was inserted only into the silent interval preceding and/or following the onset of vocalic transitions ambiguous between /p/ and /f/, or in which white noise overlaid the entire utterance. Ten listeners perceived 85% /f/s when noise was inserted only into the silent interval signaling a stop closure, 47% /f/s when noise overlaid the entire (non)words, and 1% in the control condition that contained no noise. Effects of spectro-temporal coherence seemed to have dominated perceptual outcomes, although the lexical status and position of the critical phoneme also appeared to affect responses. The results are explained more adequately by the theory of Auditory Scene Analysis than by the Motor Theory of Speech Perception.     

Interactive Effects of Exercise Status and Observer Gender on the Impressions Formed of Men

The present study was designed to examine whether men and women differ in the impressions they form of men based on exercise status. Male and female participants (N?=?183) rated a male exercise or control target on both physical and personality variables. Analysis of the physical characteristics revealed a significant condition by gender interaction where male participants rated the control target as significantly less fit (as compared to the exercise target) than did female participants. Analyses also revealed exercise status main effects for both physical and personality characteristics; exercisers were viewed in a more positive light than control targets. The present findings revealed that exercise status might have differential effects on impression formation depending on the gender of the people who are forming the impression.
