The effect of visual magnification and reduction on perceived hand size

The aim of the present study was to clarify the mechanisms underlying body understanding by examining the impact of visual experience (magnification and reduction) on perception of hand size and neutral external objects (squares). Independent groups of participants were asked to look through a 2× magnification lens, a ½-× reduction lens, or a control UV filter and to make visual size judgments about square stimuli and their hands. In Experiment 1, participants used a measuring device with unmarked wooden slats orientated in horizontal and radial/vertical space for their visual judgments. In Experiment 2, participants used an upright frontal slat for visual length judgments of their hands to eliminate any potential foreshortening in viewing the measurement apparatus. The results from the two experiments demonstrate that participants significantly underestimated both the square stimuli and their hands when they viewed them under a reduction lens. While overestimation and underestimation of squares was found for females in Experiment 2, males generally underestimated the squares. However, overestimation was not seen when the participants viewed their hands under a magnification lens. Implications of these findings are discussed.     

Counselor Ethical Reasoning: Decision‐Making Practice Versus Theory

Counselors’ decision‐making processes have received little attention in the literature. The purpose of this study was to ascertain the ethical decision‐making practices of counselors working in the field. The results of a phenomenological study indicate that linear models and an orientation to professional ethical guidelines learned in graduate training serve as a foundation, yet not a practical guide, in professional ethical decision making. The authors found that 4 themes guide counselors’ ethical decision making: personal values, clients’ best interest, transparency in decision making, and perceptions of formal training and practice. Implications for practice and counselor education are provided, with recommendations for future research.     

Antisocial Process Screening Device Subscales Predict Recidivism in an Australian Juvenile Offender Sample

The present study is the first to examine the psychometric properties of the self-report Antisocial Process Screening Device (APSD-SR), and the predictive utility of its subscales for reoffending, among Australian juvenile offenders (N?= 308, M age = 17.00, SD?=?1.49). Exploratory factor analysis supported a modified three-factor structure in which four items loaded differently to prior studies. Total APSD-SR and modified subscale scores were positively associated with criminal history and mental health problems (e.g., internalizing and externalizing problems, alcohol and substance abuse/dependence). Survival analyses indicated that youth scoring high on the APSD-SR total score were faster to reoffend nonviolently (Hazard Ratio [HR]?= 1.31, p?=?.0003) and violently (HR?=?1.42, p?=?.0003) than those scoring low. Whereas the modified grandiose-manipulative subscale predicted faster time to nonviolent recidivism (HR?=?1.18, p?=?.026) as a single predictor, when all subscales were simultaneously entered into the model only callous-unemotional (CU) traits and impulsivity predicted nonviolent recidivism (HR?=?1.19, p?=?.026 and 1.22, p?=?.015, respectively), and only impulsivity predicted violent recidivism (HR?=?1.26, p?=?.014). Findings inform current understanding of the relative contribution of adolescent psychopathy dimensions to designating a particularly high-risk group of Australian youth in custody.     

Motivational mindsets versus reasons for action: implications for the dimensionality debate in self-determination theory

Motivation and Emotion - Within self-determination theory, motivation has been treated as a unidimensional (autonomy continuum) and multidimensional (types of motivation) construct. We propose that...     

Emotions of "higher" cognition

The target article by Lindquist et al. considers discrete emotions. This commentary argues that these are but a minor part of human emotional abilities, unifying us with animals. Uniquely human emotions are aesthetic emotions related to the need for the knowledge of "high" cognition, including emotions of the beautiful, cognitive dissonances, and musical emotions. This commentary touches on their cognitive functions and origins.     

Visual search for dimensionally redundant pop-out targets: Redundancy gains in compound tasks

Two visual search experiments investigated the detection of odd-one-out feature targets redundantly defined on multiple dimensions. Targets differed from the distractors in either orientation or colour or both (redundant targets). In Experiment 1, the three types of target were presented either in separate trial blocks or randomized within blocks, and the task involved either a simple target detection response or a “compound” response based on the position of dials inside the target. Mean reaction times (RTs) were faster to redundant targets than to singly defined targets, with greater gains in simple detection than in compound tasks. Further, simple detection RTs to redundant targets were faster than the fastest RTs to singly defined targets, violating Miller's (1982) “race model inequality” (RMI). Experiment 2 showed that, with compound tasks, mean RT redundancy gains (and violations of the RMI) depend on practice. The results suggest that separate colour and orientation feature contrast signals coactivate perceptual mechanisms involved in target detection.     

What various kinds of errors tell us about lateral masking effects

Error analyses were conducted to study processes underlying lateral masking effects. Location errors (i.e., confusions with a flanking letter) occurred at a rate higher than chance, and they increased with increasing eccentricity and with decreasing spacing. In longer strings, confusions with a flanker directly adjacent to the target (which is itself laterally masked) were more frequent than with a far flanker, and these confusions also increased with increasing eccentricity and with decreasing spacing indicating that identification of the letter's form is not necessarily disturbed by adjacent characters. This was confirmed in a whole report task, where there was better recognition performance for the central letter than in partial report. Whereas in partial report, the left flanker was more often confused with the target than the right one, in whole report, the left-most letter was recognized best. The data provide evidence that positional uncertainty contributes to lateral masking effects, and that a substantial portion of positional uncertainty occurs after having identified the letter's forms.     

Employee well-being: A multilevel model linking work and nonwork domains

In this article, we review recent methodological developments that have enabled conceptual advances addressing intraindividual processes leading to psychological well-being. We contend that the introduction of dynamic assessment methodologies for sampling experiences, feelings, and behaviours on and off the job, together with the implementation of multilevel modelling strategies in organizational research on well-being, should lead to the development of richer models of employee well-being (compared to existing theoretical models). Accordingly, we develop a model of employee well-being that considers both personal and situational predictors, and both work and nonwork well-being indicators, as well as the real-time relationships between well-being antecedents and indicators across these two life spheres.
