Are spatial responses to visuospatial stimuli and spoken responses to auditory letters ideomotor-compatible tasks? Examination of set-size effects on dual-task interference

Previous studies have paired a visual-manual Task 1 with an auditory-vocal Task 2 to evaluate whether the psychological refractory period (PRP) effect is eliminated with two ideomotor-compatible tasks (for which stimuli resemble the response feedback). The present study varied the number of stimulus-response alternatives for Task 1 in three experiments to determine whether set-size and PRP effects were absent, as would be expected if the tasks bypass limited-capacity response-selection processes. In Experiments 1 and 2, the visual-manual task was used as Task 1, with lever-movement and keypress responses, respectively. In Experiment 3, the auditory-vocal task was used as Task 1 and the visual-manual task as Task 2. A significant lengthening of reaction time for 4 vs. 2 alternatives was found for the visual-manual Task 1 and the Task 2 PRP effect in Experiments 1 and 2, suggesting that the visual-manual task is not ideomotor compatible. Neither effect of set size was significant for the auditory-vocal Task 1 in Experiment 3, but there was still a Task 2 PRP effect. Our results imply that neither version of the visual-manual task is ideomotor compatible; other considerations suggest that the auditory-vocal task may also still require response selection.     

Does response interference contribute to face composite effects?

Holistic processing of faces can be measured as a failure of selective attention to one face-half under instructions to ignore the other face-half in a naming or same/different matching task. But is interference from the irrelevant half due to response interference rather than to holistic processing? Here, participants learned to name two faces “Fred” and two “Bob.” At test, composites were created from top and bottom halves of different learned faces or of a novel face, and composites were either aligned or misaligned. Naming was slower when the irrelevant half was from a different face as opposed to the same face, regardless of whether it was associated with the same name, a different name, or no name, suggesting holistic processing. Interference was eliminated when composite halves were misaligned. These results suggest that, unlike Stroop effects, composite effects are not due to response interference.     

Do the global advantage and interference effects covary?

The global precedence hypothesis has been operationally defined as a faster or earlier processing of the global than of the local properties of an image (global advantage) and as interference by processing at the global level with processing at the local level (global interference). Navon (1977) proposed an association between the global advantage and interference effects. Other studies have shown a dissociation between the two effects (e.g., Lamb & Robertson, 1988). It seems that the controversy in previous research resulted from not equalizing the eccentricities of global and local properties. In the present study, the eccentricities of the two levels were equalized by using stimuli with all their elements located along their perimeters. The results of the first experiment demonstrated that although the global level was identified faster than the local level in both the central and the peripheral locations of the visual field (global advantage), the pattern of global interference varied across the visual field. Consistency of global and local levels increased the speed of processing of the local level displayed at the center of the visual field but slowed down the processing of that level at peripheral locations. The results of Experiment 2 demonstrated that it was most likely that the variation in the pattern of global interference was determined by the variable of eccentricity, rather than by the sizes of the global and local levels.     

Are beats gestures unrelated to meaning of verbal production? Comment on Mizuguchi's view

In a recent note, Mizuguchi (2006) stated that beats are not directly related to the meaning of the production of speech. We report a number of studies that suggest the existence of a clear relationship between beats and significant parts of co-occurring speech.     

Does the direction and magnitude of cognitive change depend on initial level of ability?

Longitudinal change in five cognitive abilities was investigated to determine if the direction or magnitude of change was related to the individual's ability level. Adults between 18 and 97 years of age performed three versions of 16 cognitive tests on two occasions separated by an average of 2.7 years. In order to control for influences associated with regression toward the mean, level of ability was determined from scores on the first version of the cognitive tests on the first occasion, and across-occasion change was examined on the second and third versions. Change in every cognitive ability was significantly more negative with increased age. However, there was little indication of ability-dependent change in any of the five cognitive abilities, either in differences between composite scores, or in estimates of latent change. Although there are reasons to expect cognitive change to be less negative at either high or low levels of ability, these data suggest that neither the direction nor magnitude of change is related to initial ability when influences of regression toward the mean are controlled.     

Who exhibits more stereotypical thinking? The effect of need and ability to achieve cognitive structure on stereotyping

Need for cognitive structure (NCS) could affect stereotypical thinking. In the present paper, it is suggested that the effect of NCS on stereotyping is moderated by the ability to achieve cognitive structure (AACS). NCS is defined as the preference to use cognitive structuring (versus piecemeal processing) as a way to achieve certainty. AACS is defined as the extent to which individuals are able to use information processing processes (cognitive structuring or piecemeal) consistent with their level of NCS. Two studies were conducted to examine this hypothesis. The first examined the effect of NCS and AACS on negative stereotypes held by Israelis towards Palestinians. The second examined the effect of NCS and AACS on perceived in‐group (psychology students) and out‐group (engineering students) variability. Results of both studies showed that for high‐AACS participants, higher NCS was associated with greater stereotypical thinking, whereas for low‐AACS participants, higher NCS was associated with less stereotyping.

Dual-task interference effects on cross-modal numerical order and sound intensity judgments: the more the louder?

In the current study, cross-task interactions between number order and sound intensity judgments were assessed using a dual-task paradigm. Participants first categorized numerical sequences composed of Arabic digits as either ordered (ascending, descending) or non-ordered. Following each number sequence, participants then had to judge the intensity level of a target sound. Experiment 1 emphasized processing the two tasks independently (serial processing), while Experiments 2 and 3 emphasized processing the two tasks simultaneously (parallel processing). Cross-task interference occurred only when the task required parallel processing and was specific to ascending numerical sequences, which led to a higher proportion of louder sound intensity judgments. In Experiment 4 we examined whether this unidirectional interaction was the result of participants misattributing enhanced processing fluency experienced on ascending sequences as indicating a louder target sound. The unidirectional finding could not be entirely attributed to misattributed processing fluency, and may also be connected to experientially derived conceptual associations between ascending number sequences and greater magnitude, consistent with conceptual mapping theory.     

Eyes on the prize or nose to the grindstone? The effects of level of goal evaluation on mood and motivation

These studies tested the hypothesis that evaluating goal feedback in terms of a primary, longer term goal can be risky for future motivation. Study 1 was a 2 x 2 experiment in which framing level (primary goal/subgoal) and feedback valence (success/failure) were manipulated for participants during a verbal skills task. In the primary goal failure condition, there was increased negative mood and decreased positive mood and expectancy for subsequent trials, even while controlling for goal difficulty and importance. Study 2 was an 8-week study throughout which participants were asked to evaluate their progress regarding a primary goal (class grade goal) or subgoal (weekly study hours goal), and success or failure varied naturally. When progress was lacking, participants in the primary goal condition experienced the largest decreases in mood and expectancy. These results suggest that it is optimal to evaluate goal progress at the lower, subgoal level, particularly after failure feedback.     

Prospective relations between social support and depression: differential direction of effects for parent and peer support?

The authors tested whether deficits in perceived social support predicted subsequent increases in depression and whether depression predicted subsequent decreases in social support with longitudinal data from adolescent girls (N = 496). Deficits in parental support but not peer support predicted future increases in depressive symptoms and onset of major depression. In contrast, initial depressive symptoms and major depression predicted future decreases in peer support but not parental support. Results are consistent with the theory that support decreases the risk for depression but suggest that this effect may be specific to parental support during early adolescence. Results are also consonant with the claim that depression promotes support erosion but imply that this effect may only occur with peer support during this period.     

Picture–word interference reveals inhibitory effects of syllable frequency on lexical selection

While previous research has shown that high syllable frequency can facilitate speech production at the level of phonological/phonetic encoding, little is known about its influence on prephonological processes, specifically lexical selection. The current study used a picture–word interference (PWI) task to (a) shed light on the stages of lexical access where syllable frequency is relevant, and (b) inform as to whether lexical selection is accomplished via competition among activated word options. Participants named pictures whose names had high-frequency (HF) and low-frequency (LF) first syllables while ignoring phonologically related (same first syllable) or unrelated distractor words that were presented simultaneously. Word frequency was also manipulated, as half of the targets were HF words, and half were LF words. Results revealed inhibitory syllable frequency effects in all conditions, such that targets with HF first syllables were named more slowly than targets with LF first syllables. However, inhibitory syllable frequency effects were exacerbated in conditions thought to reflect heightened lexical competition, specifically in the presence of phonologically related distractors and for targets with low word frequency. These findings reveal novel evidence for first-syllable frequency effects on lexical selection and offer further support for models proposing delays at lexical selection due to activation of nontarget competitors.     

The present and absent object—on thinking and the capacity to symbolize

In this paper, Bion's different theories on the development of thinking will be introduced: on the one hand, his theory of thoughts as resulting from tolerance for the absence of the object, and on the other hand, dream thoughts and thoughts as resulting from the presence of the object, originally through the mother's containing function. The effects of failures in this development will be discussed; among other things, a hypertrophy of the apparatus of projective identification at the expense of thinking capacities. Briefly, a comparison will be made between a facilitating relation between container and contained and the oscillation between the paranoid-schizoid and depressive position, which Bion describes as a prerequisite for open symbolizing processes. Bion's theories and concepts will be supplemented by Winnicott's theories on the “creative illusion” and the breast/the mother as a “subjective object” as a precondition for the symbolizing capacity that later develops in the “potential space”. Very briefly, a comparison is made between Winnicott's term “the subjective object” and Segal's term “symbolic equation”. Clinical vignettes are interpolated.     

Does scientific thinking lead to success and sanity? An integration of attribution and attributional models

A motivational model is introduced that integrates conceptions of attributional antecedents with those of attributional consequences, and suggests that it is functional to make realistic attributions. This model is applied to the analysis of achievement behaviour and depression. The use of a new experimental paradigm designed to test the model's assumptions demonstrates that realistic attributions maximise performance. The model was also used to investigate whether depressives are more realistic than non-depressives. This research revealed that depressives draw more "pessimistic" conclusions from covariation information than non-depressives. In addition, depressives expect their partners to make more negative attributions about the depressives' outcomes than their partners in fact do. However, these negative views could not be traced back to faulty inferences from covariation information. Finally, research is described showing that, in addition to depressogenic attributions, certain evaluative cognitions need to be present in order to trigger depressive mood reactions.     

When does feeling of fluency matter?: how abstract and concrete thinking influence fluency effects

It has been widely documented that fluency (ease of information processing) increases positive evaluation. We proposed and demonstrated in three studies that this was not the case when people construed objects abstractly rather than concretely. Specifically, we found that priming people to think abstractly mitigated the effect of fluency on subsequent evaluative judgments (Studies 1 and 2). However, when feelings such as fluency were understood to be signals of value, fluency increased liking in people primed to think abstractly (Study 3). These results suggest that abstract thinking helps distinguish central decision inputs from less important incidental inputs, whereas concrete thinking does not make such a distinction. Thus, abstract thinking can augment or attenuate fluency effects, depending on whether fluency is considered important or incidental information, respectively.     

Otherness and the problem of evil: How does that which is other become evil?

In seeking to answer the question “How does that which is other become evil?” the author provides a discussion of four entwined aspects of the issue at stake; (1) difficulty in achieving clarity on the grammar of evil; (2) genocide as a striking illustration of otherness becoming evil; (3) the challenge of postnationalism as a resource for dealing with otherness in the socio-political arena; and (4) the ethico-religious dimension as it relates to the wider problem of evil.     

What to do? The effects of discrepancies, incentives, and time on dynamic goal prioritization

This study examined factors that influence the dynamic pursuit of multiple goals over time. As hypothesized, goal-performance discrepancies were significantly related to subsequent time allocation. Greater distance from a given goal resulted in greater time subsequently allocated to that goal. In addition, the incentives offered for goal attainment determined the relative influence of discrepancies for each goal. When the incentives for each goal were equivalent, progress toward each goal exhibited equal influence, with greater time allocated to whichever goal was furthest from completion at the time. However, with an incentive available for only 1 of the 2 goals, time allocation was largely determined by progress toward the rewarded goal. Likewise, when incentives for each task differed in their approach-avoidance framing, progress toward the avoidance-framed goal was a stronger predictor of subsequent allocation than was progress toward the approach-framed goal. Finally, the influence of goal-performance discrepancies differed as a function of the time remaining for goal pursuit. The implications for future work on dynamic goal prioritization and the provision of performance incentives are discussed.     

To do or to have? Exploring the effects of social exclusion on experiential and material purchases

Social exclusion is widespread in our modern society. In the context of marketing, consumers who are excluded will choose specific products to mitigate the negative consequences of exclusion. This research examined the effect of social exclusion on consumer preferences. Three experimental studies were conducted to test whether consumers experiencing social exclusion would choose specific kinds of purchases. The results of the three studies provided convergent support for the notion that consumers who feel socially excluded exhibit a preference for experiential purchases over material purchases. It therefore appears that experiential purchases can more effectively compensate for the relational needs caused by social exclusion. The effect was stronger for socially excluded individuals exhibiting more interdependent self‐construal than for those exhibiting a more independent self‐construal. These results indicate that social impact is an antecedent of experiential purchases, and they shed light on an important mechanism to alleviate the negative effects of social exclusion.     

Are the fruits of research available to all? The effects of sex and academic rank on reprint-sending behavior

There is considerable evidence in the psychological literature that perceived status often has a major effect on behavior. The primary purpose of the present study was to examine the effects of two status variables in an academic setting by monitoring reprint-sending behavior. Reprints were requested from 1,200 authors of psychological articles by men and women of varying academic rank. Neither sex nor academic rank of requester had any significant effect on the total number of responses returned. However, male requesters received responses significantly faster than did female requesters. In addition, subsequent analyses indicated that reprint requests were more likely to be honored by male authors than by female authors.     

The effects of problem content,instructions, and verbalization procedure on Wason’s selection task

This study examined various hypotheses for facilitation on Wason’s four-card selection task by means of a factorial experiment. The factors were memory cuing vs. nonmemory cuing content, violation vs. true-false instructions, and verbalization procedure. The results indicated that memory cuing content may be a necessary and sufficient condition for facilitation, but that the amount of facilitation is affected by the type of instructions. Verbalization procedure had no effects, but this may have been due to the subjects’ failure to comply completely with the various verbalization instructions. An explanation of the results that assumes that content and instructions determine the cognitive processing load of the task and hence the solution strategies employed is considered.
