Negative triangles: simple geometric shapes convey emotional valence

It has been suggested that downward pointing triangles convey negative valence, perhaps because they mimic an underlying primitive feature present in negative facial expressions (Larson, Aronoff, and Stearns, 2007). Here, we test this proposition using a flanker interference paradigm in which participants indicated the valence of a central face target, presented between two adjacent distracters. Experiment 1 showed that, compared with face flankers, downward pointing triangles had little influence on responses to face targets. However, in Experiment 2, when attentional competition was increased between target and flankers, downward pointing triangles slowed responses to positively valenced face targets, and speeded them to negatively valenced targets, consistent with valence-based flanker compatibility effects. These findings provide converging evidence that simple geometric shapes may convey emotional valence.     

Wanting,having, and satisfaction: examining the role of desire discrepancies in satisfaction with income

In 3 studies, the authors tested the predictors of income satisfaction, examining whether discrepanc between the things people have and the things they desire predict satisfaction. Study 1 manipulated the desirability of items that can be purchased with participants' income, and showed that their satisfaction with that income depended on the desirability of these items. Study 2 demonstrated that whether people's income enabled them to purchase the things they desired influenced their satisfaction with income. Study 3 found that the effect of comparisons with a person's past on income satisfaction is completely mediated by one's desires; and the effect of social comparison on income satisfaction is partially mediated by desires. Thus, desires play a pivotal role in determining people's satisfaction with income.     

What Constitutes a Good Life? Cultural Differences in the Role of Positive and Negative Affect in Subjective Well‐Being

ABSTRACT East Asians and Asian Americans report lower levels of subjective well-being than Europeans and European Americans. Three studies found support for the hypothesis that such differences may be due to the psychological meanings Eastern and Western cultures attach to positive and negative affect. Study 1 demonstrated that the desire to repeat a recent vacation was significantly predicted by recalled positive affect—but not recalled negative affect—for European Americans, whereas Asian Americans considered both positive and negative affect. Study 2 replicated this effect in judging satisfaction with a personal friendship. Study 3 linked changes in European Americans' life satisfaction to everyday positive events caused by the self (vs. others) and changes in Japanese life satisfaction to everyday negative events caused by others (vs. the self). Positive affect appears particularly meaningful for European Americans and negative affect for Asian Americans and Japanese when judging a satisfying vacation, friendship, or life.     

Evaluation of the Dispositional Hope Scale in injury survivors

Hope is a higher-order cognitive construct that encompasses the belief in one’s ability to accomplish personal goals. Hope has been conceptualised as consisting of two constructs – Pathways (the individual’s perceived means available to achieve goals) and Agency (belief in ones ability to succeed in using the identified Pathways). This study aimed to validate a measure of hope, the Dispositional Hope Scale (DHS: [Snyder, C. R., Harris, C., Anderson, J. R., Holleran, S. A., Irving, L. M., Sigman, S. T., et al. (1991). The will and the ways: Development and validation of an individual differences measure of hope. Journal of Personality and Social Psychology, 60(4), 570–585]) in a large sample of traumatic injury survivors (N = 1025). The findings support the psychometric properties of the scale, as well as the two-factor structure of Agency and Pathways, in this population. This study provides support for the use of the DHS as a measure of hope in traumatised populations.     

An investigation into some of the underlying associative verbal processes of the stroop colour effect

The Stroop test was examined to throw some light on the verbal basis of the test. When words are presented printed in the wrong colour it is found that the written word provides more interference with response to the colour of print than occurs the other way round (the Stroop effect). It was shown that, by allowing subjects to match the colour of the print with colour patches instead of words, the interference due to the written word can be considerably reduced. In a further experiment, associations were formed by the subjects between nonsense syllables and colours in the course of a paired-associate learning task. When nonsense syllables were presented printed in colours different from those associated with them, it was found that the interference effects depended upon the direction of the stimulus-response association in the paired-associate experiment. It is concluded that the underlying processes in the Stroop effect are primarily verbal and depend partly upon the directionality of previously established verbal associations.     

Fast color grouping and slow color inhibition: evidence for distinct temporal windows for separate processes in preview search

The authors report 4 experiments that examined color grouping and negative carryover effects in preview search via a probe detection task (J. J. Braithwaite, G. W. Humphreys, & J. Hodsoll, 2003). In Experiment 1, there was evidence of a negative color carryover from the preview to new items, using both search and probe detection measures. There was also a negative bias against probes on old items that carried the majority color in the preview. With a short preview duration (150 ms) carryover effects to new items were greatly reduced, but probe detection remained biased against the majority color in the old items. Experiments 2 and 4 showed that the color bias effects on old items could be reduced when these items had to be prioritized relative to being ignored. Experiment 3 tested and rejected the idea that variations in the probability of whether minority or majority colors were probed were crucial. These results show that the time course of color carryover effects can be separated from effects of early color grouping in the preview display: Color grouping is fast, and inhibitory color carryover effects are slow.     

Revisiting preview search at isoluminance: new onsets are not necessary for the preview advantage

It has been argued that search performance under preview conditions relies on automatic capture by luminance onsets (Donk & Theeuwes, 2001). We present three experiments in which preview search was examined with both isoluminant and nonisoluminant items (e.g., as defined by luminance onsets). Experiment 1 provided evidence against the automatic capture of attention by onsets. Search benefited when onset previews were followed by new onset stimuli, as compared with a full-set baseline matched for the number of new onsets but in which half the distractors appeared simultaneously at isoluminance. Furthermore, both Experiments 1 and 2 established a preview advantage when isoluminant targets followed onset previews, when compared with appropriate full-set baselines. Experiment 3 replicated this result, while showing that the preview benefit was disrupted by dual-task interference. The data indicate that new onsets are not necessary to generate a preview advantage in search. We discuss the data in terms of search's benefiting from active inhibition of old onset-defined stimuli.     

Counterfactual thinking and the first instinct fallacy

Most people believe that they should avoid changing their answer when taking multiple-choice tests. Virtually all research on this topic, however, has suggested that this strategy is ill-founded: Most answer changes are from incorrect to correct, and people who change their answers usually improve their test scores. Why do people believe in this strategy if the data so strongly refute it? The authors argue that the belief is in part a product of counterfactual thinking. Changing an answer when one should have stuck with one's original answer leads to more "if only . . ." self-recriminations than does sticking with one's first instinct when one should have switched. As a consequence, instances of the former are more memorable than instances of the latter. This differential availability provides individuals with compelling (albeit illusory) personal evidence for the wisdom of always following their 1st instinct, with suboptimal test scores the result.     

When a reappearance is old news: visual marking survives occlusion

Performance in a visual search task becomes more efficient if half of the distractors are presented before the rest of the stimuli. This "preview benefit" may partly be due to inhibition of the old (previewed) items. The preview effect is abolished, however, if the old items offset briefly before reappearing (D. G. Watson & G. W. Humphreys, 1997). The authors examined whether this offset effect still occurred if the old items undergo occlusion. Results show that a preview benefit was found when the old items were occluded but not otherwise, consistent with the idea of top-down attentional inhibition being applied to the old items. The preview benefit is attenuated, however, by movement of the irrelevant stimuli in the displays.     

On the efficiency of drawing computer-generated line stimuli: Rectangles can be faster than lines

A simple method is presented for optimizing the efficiency of drawing line stimuli in Turbo Pascal. It involves the substitution of Rectangle and Bar commands for Line commands and results in time savings of up to 90%. The savings are most consistent for horizontal lines, although some savings may also be made for vertical lines. The effects of different graphics libraries, graphics modes, and hardware configurations are discussed. The method proves especially useful in improving the spatiotemporal resolution of on-line-generated motion displays.
