Spatial compatibility interference effects: a double dissociation between two measures

ABSTRACT

In spatial compatibility tasks, when the spatial location of a stimulus is irrelevant it nevertheless interferes when a response is required in a different spatial location. For example, response with a left key-press is slowed when the stimulus is presented to the right as compared to the left side of a computer screen. However, in some conditions this interference effect is not detected in reaction time (RT) measures. It is typically assumed that the lack of effect means the irrelevant spatial code was not analysed or that the information rapidly decayed before response. However, we show that even in conditions where there appears to be no spatial interference when measuring RTs, effects can nevertheless be detected after response when recording facial electromyography responses. This dissociation between two measures highlights the importance of diverging methods to investigate visuomotor processes as conclusions based on only one measure can be misleading.     

Target localization after saccades and at fixation: Nontargets both facilitate and bias responses

ABSTRACT

The image on our retina changes every time we make an eye movement. To maintain visual stability after saccades, specifically to locate visual targets, we may use nontarget objects as “landmarks”. In the current study, we compared how the presence of nontargets affects target localization after saccades and during sustained fixation. Participants fixated a target object, which either maintained its location on the screen (sustained-fixation trials), or displaced to trigger a saccade (saccade trials). After the target disappeared, participants reported the most recent target location with a mouse click. We found that the presence of nontargets decreased response error magnitude and variability. However, this nontarget facilitation effect was not larger for saccade trials than sustained-fixation trials, indicating that nontarget facilitation might be a general effect for target localization, rather than of particular importance to post-saccadic stability. Additionally, participants’ responses were biased towards the nontarget locations, particularly when the nontarget-target relationships were preserved in relative coordinates across the saccade. This nontarget bias interacted with biases from other spatial references, e.g., eye movement paths, possibly in a way that emphasized non-redundant information. In summary, the presence of nontargets is one of several sources of reference that combine to influence (both facilitate and bias) target localization.     

Moving thoughts make for moving targets: Capturing time-sensitive effects in global/local processing

ABSTRACT

We examined the time-course of global/local processing with the goal of describing average change over time and individual differences in that change, namely, variability in level (intercept) and magnitude (slope) of change. To do so, we probed global/local processing across a broad time-course so that effects of time may be estimated from a randomly sampled set of time-points from the “true” population of time-points. Results showed that, on average, processing transitioned from global to local dominance; variation around this average, however, pointed to an ebb-and-flow in dominance rather than strict linear change.     

Constructing sacred space under the forces of the market: A study of an ‘upper-floor’ Protestant church in Hong Kong

In Hong Kong, over half of the Protestant churches are located in the upper-floor units in commercial and residential buildings. Because of their physical locations, these churches are sometimes dubbed ‘upper-floor churches’. Unlike those that occupy stand-alone religious buildings or dwell in church-run schools and social service centres, these are often invisible in the landscapes of the city. Through analysis of a case study, this paper aims to explore the spatial practices that a Protestant community has adopted in acquiring, representing, and ritualising a business unit in a residential high-rise for building up their church. Our analysis of the case study shows that in a metropolis like contemporary Hong Kong, the construction of sacred space is full of tensions between utilitarian calculations and concerns of human relations and religious values. While the congregation had been very creative in transforming a commercial unit into a religious site, it did not show much awareness of the oppressive powers of the capitalist market and had a strong tendency to represent its spatial practices as commodities for consumption.     

A Survey of Dynamic Principles Governing Memory

A triadic coalition game was structured as an achievement-oriented situation by inclusion of a skill-based game task. Deductions regarding coalition partner choices were derived from Atkinsons' model of achievement motivation with the expectation that achievement-oriented players (Ms < Maf) would prefer moderate-risk strategy options while failure-avoidant players (Maf < Ms) would avoid moderate-risk strategies.

Observation was made of the coalition partner preferences of 126 college sophomore males and females who played the game in same-sex triads. The Ss were categorized into motive configuration groups on the basis of scores derived from the Test of Insight and the Test Anxiety Questionnaire.

The results were supportive of the hypotheses, since the Ms < Maf group chose moderate-risk coalition options more frequently than did the Maf < Ms group. By contrast the Maf < Ms group chose low-risk strategies and tended to avoid moderate-risk coalition options. While other coalition-game studies have shown differences in strategy behavior between males and females, sex differences did not occur in the present game. The lack of sex differences was explained by the high level of concern for winning among members of both sexes generated by the achievement nature of the game task.     

Calibration and Alignment are Separable: Evidence From Prism Adaptation

In 2 prism adaptation experiments, the authors investigated the effects of limb starting position visibility (visible or not visible) and visual feedback availability (early or late in target pointing movements). Thirty-two students participated in Experiment 1 and 24 students participated in Experiment 2. Independent of visual feedback availability, constant error was larger and variable error was smaller for target pointing when limb starting position was visible during prism exposure. Independent of limb starting position visibility, aftereffects of prism exposure were determined by visual feedback availability. Those results support the hypothesis that calibration is determined by limb starting position visibility, whereas alignment is determined separately by visual feedback availability.     

Attentional bias towards angry faces is moderated by the activation of a social processing mode in the general population

ABSTRACT

Dot-probe studies usually find an attentional bias towards threatening stimuli only in anxious participants, but not in non-anxious participants. In the present study, we conducted two experiments to investigate whether attentional bias towards angry faces in unselected samples is moderated by the extent to which the current task requires social processing. In Experiment 1, participants performed a dot-probe task involving classification of either socially meaningful targets (schematic faces) or meaningless targets (scrambled schematic faces). Targets were preceded by two photographic face cues, one angry and one neutral. Angry face cues only produced significant cueing scores (i.e. faster target responses if the target replaced the angry face compared to the neutral face) with socially meaningful targets, not with meaningless targets. In Experiment 2, participants classified only meaningful targets, which were either socially meaningful (schematic faces) or not (schematic houses). Again, mean cueing scores were significantly moderated by the social character of the targets. However, cueing scores in this experiment were non-significant in the social target condition and significantly negative in the non-social target condition. These results suggest that attentional bias towards angry faces in the dot-probe task is moderated by the activation of a social processing mode in unselected samples.     

情境模型中时间和空间维度更新的相互影响

运用移动窗口技术考察情境模型中时间和空间维度同时或序列转变时二者间的相互关系。结果发现：(1)时间和空间同时转变时, 二者存在易化关系, 但时间对空间的易化作用更大; (2)当二者序列转变时, 以中文为材料的结果只发现时间对空间的易化关系, 而以英语为材料的结果则发现存在双向易化关系, 但时间对空间的易化作用更大。据此, 情境模型中的时间和空间维度更新的捆绑－预期假设得到证明。
