Conditional discrimination and equivalence relations: A theoretical analysis of control by negative stimuli

A detailed analysis is presented of the ways in which control by the negative stimulus in two-comparison conditional discriminations may be expected to affect the outcome of tests for the properties of equivalence relations. Control by the negative stimulus should produce the following results: (a) no observable effect on symmetry tests; (b) reflexivity test results should look like “oddity” rather than “identity”; and (c) transitivity tests that involve an odd number of nodes should yield results that are 100% opposite to tests that involve an even number of nodes. The analysis also considers the effects of variation in the type of comparison-stimulus control between and within baseline conditional discriminations. Methods are suggested for experimentally regulating the type of control, and for verifying the predictions that the analysis generates. If suggested experiments continue to support the analysis, investigators who use two-comparison conditional discriminations to study equivalence relations will either have to control explicitly whether the positive or the negative comparison governs their subjects' choices, or they will have to abandon two comparisons and use three or more comparisons instead.     

Effects of long-term meditation practice on attentional biases towards emotional faces: An eye-tracking study

Attentional biases towards affective stimuli reflect an individual balance of appetitive and aversive motivational systems. Vigilance in relation to threatening information reflects emotional imbalance, associated with affective and somatic problems. It is known that meditation practice significantly improves control of attention, which is considered to be a tool for adaptive emotional regulation. In this regard, the main aim of the present study was to evaluate the influence of meditation on attentional bias towards neutral and emotional facial expressions. Eyes were tracked while 21 healthy controls and 23 experienced meditators (all males) viewed displays consisting of four facial expressions (neutral, angry, fearful and happy) for 10 s. Measures of biases in initial orienting and maintenance of attention were assessed. No effects were found for initial orienting biases. Meditators spent significantly less time viewing angry and fearful faces than control subjects. Furthermore, meditators selectively attended to happy faces whereas control subjects showed attentional biases towards both angry and happy faces. In sum we can conclude that long-term meditation practice adaptively affects attentional biases towards motivationally significant stimuli and that these biases reflect positive mood and predominance of appetitive motivation.     

Preferences for sexual dimorphism on attractiveness levels: An eye-tracking study

Previous studies on sexual dimorphism showed feminine preferences in female faces and mixed findings in male faces by choosing which is more attractive in a pair of a masculine face and a feminine face. However, very little is known about how people make fine-grained visual assessments of such images and the attractiveness levels of faces are not received much attention. Recently a large number of androgynous stars appear in the media, which triggers a hot phenomenon of imitating them. Here we examine the influence of androgynous stars on people’s facial preferences for sexual dimorphism in male and female faces on different attractiveness levels using eye-tracking techniques. In male faces we found both male and female participants preferred masculine faces to androgynous faces in high attractiveness, but mixed results in low attractiveness. In female faces we found both male and female participants preferred feminine faces to androgynous faces in high attractiveness, but no preferences in low attractiveness. Results suggest that attractiveness levels of faces might be a factor causing inconsistency in sexual dimorphism preference for male faces and that androgynous faces are not preferred, which reveals that androgynous phenomenon might not be caused by facial attractiveness.     

Effects of tDCS over the right DLPFC on attentional disengagement from positive and negative faces: An eye-tracking study

The aim of this study was to increase insight in the neural substrates of attention processes involved in emotion regulation. The effects of right dorsolateral prefrontal cortex (i.e., DLPFC) stimulation on attentional processing of emotional information were evaluated. A novel attention task allowing a straightforward measurement of attentional engagement toward, and attentional disengagement away from emotional faces was used. A sample of healthy participants received 20 minutes of active and sham anodal transcranial direct current stimulation (i.e., tDCS) applied over the right DLPFC on 2 separate days and completed the attention task after receiving real or sham stimulation. Compared to sham stimulation, tDCS over the right DLPFC led to impairments in attentional disengagement from both positive and negative faces. Findings demonstrate a causal role of right DLPFC activity in the generation of attentional impairments that are implicated in emotional disturbances such as depression and anxiety.     

积极接触与消极接触对群际关系的影响

群际接触研究中存在的“积极偏向”阻碍了对群际接触的全面认知, 因而, 近年来消极接触开始被纳入研究之列。当前的积极接触和消极接触研究以问卷法为主, 另外还涉及内容分析、社会网络分析以及实验法。积极接触和消极接触分别会提升和恶化群际关系, 群际情绪、群际信任在其中起中介作用, 权威主义、亲密性起调节作用。在积极接触效应和消极接触效应的关系上, 存在不对称性检验和交互作用检验两种研究思路, 并均得到了实证研究证据的支持。未来研究需要进一步考察不同效价接触, 尤其是消极接触的泛化效应, 拓展积极接触和消极接触的效应范围, 完善积极接触和消极接触的作用机制, 并进一步探索影响积极接触和消极接触不对称性效应的因素。     

The effects of trait and state anxiety on attention to emotional images: An eye-tracking study

Attentional biases for threatening stimuli have been implicated in the development of anxiety disorders. However, little is known about the relative influences of trait and state anxiety on attentional biases. This study examined the effects of trait and state anxiety on attention to emotional images. Low, mid, and high trait anxious participants completed two trial blocks of an eye-tracking task. Participants viewed image pairs consisting of one emotional (threatening or positive) and one neutral image while their eye movements were recorded. Between trial blocks, participants underwent an anxiety induction. Primary analyses examined the effects of trait and state anxiety on the proportion of viewing time on emotional versus neutral images. State anxiety was associated with increased attention to threatening images for participants, regardless of trait anxiety. Furthermore, when in a state of anxiety, relative to a baseline condition, durations of initial gaze and average fixation were longer on threat versus neutral images. These findings were specific to the threatening images; no anxiety-related differences in attention were found with the positive images. The implications of these results for future research, models of anxiety-related information processing, and clinical interventions for anxiety are discussed.

采用固定反应范式和自由反应范式, 通过创设语用情景, 考察不同权力关系对消极特质否定句使用偏向的影响。结果表明：(1)低权力者评价高权力者时, 被试倾向于使用否定方式(如“不聪明的”), 并认为否定的表述方式合适性较高, 出现否定偏向; 而高权力者评价低权力者, 或者权力平级时则没有否定偏向的出现, 肯定表述(如“愚蠢的”)被更多使用; (2)权力平级时, 社会距离会影响消极特质否定句的使用, 社会距离越远, 消极特质否定句的使用越少; 社会距离越近, 消极特质否定句的使用越多。结果表明, 权力关系与社会距离是影响消极特质否定句使用偏向的重要因素。     

Curriculum-based measurement of math problem solving: A methodology and rationale for establishing equivalence of scores

The purpose of this article is to discuss curriculum-based measurement (CBM) as it is currently utilized in research and practice and to propose a new approach for developing measures to monitor the academic progress of students longitudinally. To accomplish this, we first describe CBM and provide several exemplars of CBM in reading and mathematics. Then, we present the research context for developing a set of seven curriculum-based measures for monitoring student progress in math problem solving. The rationale for and advantages of using statistical equating methodology are discussed. Details of the methodology as it was applied to the development of these math problem solving measures are provided.     

Parental divorce: long-term effects on mental health, family relations and adult sexual behavior

Specific long term effects of parental divorce were examined in a sample of 179 Icelanders, 20 to 30 years of age. The participants answered the Borromean Family Index, the Affect Balance Scale and a number of questions on sexual behavior and attitudes towards marriage and divorce. Results showed that compared to adults whose parents remained married, those of divorced parents reported more negative emotional experiences at the time of the study and had looser family ties. They also had greater number of short love affairs, had their first love affair at a younger age, had a greater number of sexual partners, and were younger at the time of their first sexual intercourse than adults whose parents remained married.     

The equivalence of computerized and paper-and-pencil psychological instruments: Implications for measures of negative affect

The use of computerized psychological assessment is a growing practice among contemporary mental health professionals. Many popular and frequently used paper-and-pencil instruments have been adapted into computerized versions. Although equivalence for many instruments has been evaluated and supported, this issue is far from resolved. This literature review deals with recent research findings that suggest that computer aversion negatively impacts computerized assessment, particularly as it relates to measures of negative affect. There is a dearth of equivalence studies that take into account computer aversion’s potential impact on the measurement of negative affect. Recommendations are offered for future research in this area.     

Schematic influences of rape myth acceptance on visual information processing: An eye-tracking approach

Schematic influences of rape myth acceptance (RMA) on visual information processing were studied. After reading a short text on a rape case, students viewed a “police photograph” of the plaintiff's living room, where the rape allegedly happened, while their eye-movements were recorded. The photograph contained two myth-consistent cues, one being expected in the situation (wine bottle and glasses), the other unexpected (poster of a nude male). Results of Study 1 (N = 60) showed that participants higher in RMA fixated the expected cue both earlier and less long, which may indicate hypervigilance and greater ease of processing, respectively. Higher RMA also predicted longer initial fixation of the unexpected cue. These processing differences mediated participants' verdicts and blame judgments. In Study 2 (N = 30), participants' level of RMA was manipulated experimentally via social norm feedback. This manipulation significantly affected eye-movement patterns for the expected myth-consistent cue. Results support the notion that RMA actively guides visual information processing of relevant stimuli.     

The effects of three stimulus‐equivalence testing conditions on emergent US geography relations of children diagnosed with autism

Two children with autism were trained in US geography using a match to sample procedure. Different testing procedures commonly used in stimulus equivalence research were compared, including some conditions with reinforcement for responding to enhance motivation. Both children were able to master the trained geography relations and emergent stimulus relations were also noted. All three testing procedures produced similar effects, suggesting that incorporation of procedures to enhance motivation to respond does not invalidate testing in a stimulus equivalence preparation.

Effect size indices for analyses of measurement equivalence: understanding the practical importance of differences between groups

Because of the practical, theoretical, and legal implications of differential item functioning (DIF) for organizational assessments, studies of measurement equivalence are a necessary first step before scores can be compared across individuals from different groups. However, commonly recommended criteria for evaluating results from these analyses have several important limitations. The present study proposes an effect size index for confirmatory factor analytic (CFA) studies of measurement equivalence to address 1 of these limitations. The application of this index is illustrated with personality data from American English, Greek, and Chinese samples. Results showed a range of nonequivalence across these samples, and these differences were linked to the observed effects of DIF on the outcomes of the assessment (i.e., group-level mean differences and adverse impact).     

The effects of face inversion on the perception of long-range and local spatial relations in eye and mouth configuration

A recent study hypothesized a configurational anisotropy in the face inversion effect, with vertical relations more difficult to process. However, another difference in the stimuli of that report was that the vertical but not horizontal shifts lacked local spatial references. Difficulty processing long-range spatial relations might also be predicted from a relevance-interaction explanation, which proposes that in inverted faces, spatial relations are processed efficiently only within high-relevance local regions. The authors performed 2 experiments to distinguish between these hypotheses. Experiment 1 showed that the inversion effect for vertical shifts of the eyes alone was more similar to that for horizontal eye shifts than for vertical shifts of the eyes and eyebrows. In Experiment 2, focused attention reduced the inversion effect for vertical mouth position more than that for vertical shifts of the eyes and brows. The authors concluded that face inversion impairs the perception of both local spatial relations in low-relevance regions and long-range spatial relations extending across multiple facial regions, consistent with a loss of efficient whole-face processing of the spatial relations between features.
