Effect propensity

In a choice between two options, decision makers can often be roughly divided into three groups: those who strongly prefer the first option, those who strongly prefer the second option, and those whose choices are most sensitive to the specific conditions (Switchers). In any reference state, such as the experimental control, Switchers’ choices are unlikely to be exactly equally divided between the options, which potentially creates a ceiling effect among those most susceptible to influence by the particular conditions or experimental manipulations. The limited growth potential of the option favored by Switchers in the reference state can produce “effect propensity,” whereby any condition or manipulation applied to the reference state is more likely to increase the share of the other option. We test this proposition in a series of studies in the context of choices between safe and risky options and between lower-price/quality and higher-price/quality options. The results indicate that a large majority of conceptually unrelated manipulations tend to increase the choice share of risky and higher-price/quality options. This effect propensity can be reversed when the risky and higher-price/quality options are the status quo alternatives or asymmetrically dominating in the reference state. Alternative explanations for effect propensity are examined. We discuss the implications of effect propensity for the interpretation of research findings, the selection of controls, and theory tests.

认知需求和认知闭合需求对风险决策中外语效应的影响

外语效应指相比于母语背景,个体在外语背景下风险决策偏差会降低。针对影响外语效应的因素研究大多聚焦于外部因素和与个体外语水平相关的因素,少有研究探讨认知风格的作用。本研究通过524名成人被试,探索认知需求和认知闭合需求对外语效应的影响。结果表明:(1)风险决策中存在外语效应,相比于母语背景,外语背景下框架效应被削弱,且个体更偏向风险寻求。(2)对于认知需求和认知闭合需求都高或都低的个体,语言类型会影响风险决策,在母语环境下倾向于风险规避,在外语环境下倾向于风险寻求;而对于认知需求和认知闭合需求高低不一致的个体,语言类型对其风险决策倾向的影响不显著。本研究为认知风格如何综合影响风险决策提供了进一步的证据。

Reshaping Couple Configurations that Get in the Way of Relationship Repair and Healing

In the context of relationship trauma, partners' reactive patterns of engagement can disrupt and derail attempts at relationship correction and healing. A circumplex typology of couple patterns of engagement in relational trauma context is defined in terms of partners' underlying views of self in relation to other (VSIRO). VSIRO is conceptualized along a continuum anchored at opposite poles by inflated (self-aggrandizing) versus collapsed (self-abnegating) VSIRO, with a balanced (egalitarian) VSIRO, characterized by accountability and forbearance, as the target position. The circumplex model delineates four problematic couple configurations—a dejected couple, a taker–enabler couple, an ultimate fighting couple, and a debtor–collector couple. Where problematic engagement occurs, therapists need to reshape couple engagement toward the balanced, egalitarian position prior to relational trauma work. Clinical vignettes depict these couples and springboard an analysis of unique needs and interventions associated with each couple configuration. Reshaping couple patterns of engagement using a circumplex model of couple configurations is an essential prerequisite to effective and ethical relational trauma work.     

Working with issues of difference in supervision of counselling

In this paper, I describe some meanings of the word ‘difference’ and connect these to aspects of the supervisory relationship, roles, tasks and process. Describing some theoretical views of the origins of the sense of difference and the significance of this for the work of the supervisor and supervisee, I suggest that, for maturational processes to take place, the development of a potential space is essential. Ideas are drawn from cross-cultural counselling, but are applied broadly to the client-counsellor-supervisor triangle of relationship, particularly the emphasis on the need to address difference and the possibility of proxy-self communication. I give examples from supervisory practice to illustrate.     

Horizontal and vertical Simon effect: different underlying mechanisms?

Reaction times are usually faster when stimulus and response occur at the same location than when they do not, even if stimulus location is irrelevant to the task (Simon effect). This effect was found with both horizontal and vertical stimulus-response arrangements. The same mechanisms have been proposed to be involved in either case. Here, we compared a horizontal and a vertical Simon task by means of a RT time-course analysis of the Simon effect. Also, we analysed the lateralised readiness potential (LRP), an index of covert response-preparation processes. In the horizontal task, the Simon effect decays over time and pre-activation occurs above the motor cortex ipsilateral to the stimulus. In contrast, the Simon effect does not decay over time and no early incorrect LRP deflection is observed in the vertical task. These findings suggest that typical activation accounts can fit only the horizontal Simon effect, while a translation explanation is more suitable for the vertical Simon effect.     

Identification of stuttering in bilingual Lebanese children across two presentation modes

The goals of this study were to investigate whether Lebanese speech-language pathologists (SLPs) are accurate at identifying stuttering in bilingual children, to examine whether the use of video-recordings instead of audio-recordings allows for better analyses, and to explore factors that may affect the SLPs’ judgments. In phase 1, 32 SLPs listened to narrative samples in Lebanese Arabic of 6 children who do not stutter (CWNS) and 2 who stutter (CWS). They were instructed to label each child as stuttering or not, and to explain what motivated their decisions. Afterwards, they were asked to provide background information by means of a questionnaire. In phase 2, they were asked to judge the same speech samples on the basis of video-recordings, and to explain for each child which speech characteristics they relied on to make their decisions. The results showed that misidentification happens frequently, is significantly more likely to happen with CWNS than with CWS, but also varies within these categories. Moreover, the use of video-recordings does not provide more reliable analyses of speech disfluencies, and speech samples’ characteristics and bilingual profile rather than SLPs’ characteristics seem to influence the judgments. Qualitative analyses indicate that, in the current study, misidentification may be driven by neglecting or misinterpreting physical concomitants. In general, the findings indicate that identifying and analyzing speech fluency behaviors remain a challenging perceptual task, which underlies the need for developing consistent methods for training students and clinicians in identifying stuttering, especially in a bilingual context.     

复杂情境下不同角度及思维方式的决策表现差异:决策视角-心理距离的作用

本研究运用2个行为实验探讨了复杂情境下自我决策、为他人决策和预期他人决策在无意识思维方式和有意识思维方式下的决策表现差异。实验1发现复杂情境中无意识思维方式下,自我决策和为他人决策的决策表现显著优于预期他人决策,自我决策和为他人决策表现没有显著差异。实验2发现复杂情境中有意识思维时,在陌生人条件下,为他人决策表现分数显著高于自我决策与预期他人决策,自我决策和预期他人决策表现无显著差异;在朋友条件下,为他人决策和预期他人决策的决策表现显著优于自我决策,为他人决策和预期他人决策表现无显著差异。研究结果支持了本文提出的决策视角-心理距离作用假设(the Perspective-Distance Effect Hypothesis,PDEH)。     

Inter-word eye behaviour during reading is not invariant to character size: Evidence against systematic saccadic range error in reading

The present study re-investigated the effect of character size on eye behaviour during reading, in order to test McConkie, Kerr, Reddix, and Zola's (1988 McConkie, G. W., Kerr, P. W., Reddix, M. D., & Zola, D. (1988). Eye movement control during reading: I. The location of initial eye fixations on words. Vision Research, 28(10), 1107–1118. doi:10.1016/0042-6989(88)90137-X[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) Saccadic Range Error (SRE) hypothesis. This assumes that saccades are biased to move the eyes a constant, optimal distance in the task (i.e., range error), while aiming at the centre of peripherally selected target words. Results showed in contradiction with this hypothesis, (1) that the linear relationship between the eye launch site and the mean landing sites in words is not invariant to character size, and (2) that the optimal launch-site distance to the centre of words varies depending on the spatial extent of the words, and differs from the mean length of saccades in the task. We propose an alternative, Center-of-Gravity hypothesis, which a priori accounts for the launch-site effect and its variations with character size, and suggests that research in reading may benefit from reconsidering the role of character size.
