The role of attention in automatization: Does attention operate at encoding, or retrieval, or both?

In this research, we investigated whether attention operates in the encoding of automatized information, the retrieval of automatized information, or in both cases. Subjects searched two-word displays for members of a target category in focused-attention or divided-attention conditions that were crossed with block (training vs. transfer). To see whether subjects encoded all available items or only attended items, we compared performance for subjects in different training conditions but in the same transfer condition. Subjects encoded attended items. To see whether subjects retrieved all the items they had in memory, or only items associated with that to which they were attending at retrieval, we compared performance for subjects in the same training conditions but in different transfer conditions. Subjects retrieved attended items. Attention was found to operate at both encoding and retrieval. These findings support the instance theory of automaticity, which predicts the role of attention at encoding and retrieval     

Toupee or not toupee? The role of instructional set,centrality, and relevance in change blindness

The influence of instructional set, centrality, and relevance on change blindness was examined. In a one-shot paradigm, participants reported alterations of items across pairs of driving scenes under two different instructional conditions. Alterations involved either relocations or disappearances of the same items and included driving-relevant and driving-irrelevant alterations to items of central and marginal interest. Three main findings emerged: Centrality was not a function of driving relevance/meaningfulness, disappearances of central interest items were identified significantly more often than positional changes to them, and instructions highlighting the importance of the task to driving attenuated change blindness. The possible role of a simple listing strategy in mediating successful identification of alterations is discussed. Together, the findings demonstrate that cognitive factors play an important role in change blindness.     

The syllable’s role in speech production: Are syllables chunks, schemas, or both?

Two experiments, one using the masked priming technique combined with very brief prime exposures and the other using a new technique, the induction technique, were run in order to investigate the role of syllabic structure in speech production. Experiment 1 (masked priming) showed no effect when primes shared only the abstract syllabic structure without the phonological content, whereas the same picture stimuli produced a syllabic priming effect in Ferrand, Segui, and Grainger (1996, Experiment 4) when primes corresponded to full syllables. In contrast, the results of Experiment 2 (induction) showed that picture naming latencies were significantly faster when subjects had first read aloud a set of words with the same syllabic structure than when these words did not share the syllabic structure with the picture target. This result was also observed when the set was composed of nonwords. These results demonstrate that the abstract syllabic structure (independently of its phonological content) plays an important role in speech production depending on the task used.     

Causes of boredom: The person,the situation,or both?

Some theories emphasize the role of the situation, some emphasize the role of the person, and some emphasize the interaction between situation and person in causing boredom. The present study examines these models by determining whether boredom propensity (person) and/or experimental condition (situation) independently or in interaction affected state boredom. The study also examined the relative contribution of behavioural activation and inhibition to state boredom. Boredom propensity and condition significantly and independently predicted state boredom, as did the interaction between behavioural inhibition and condition. Implications are discussed, including the possibility of two distinct causes of boredom.     

The flanker effect does not reflect the processing of “task-irrelevant” stimuli: Evidence from inattentional blindness

It is often the case that stimuli (or aspects of a stimulus) are referred to as being “task-irrelevant.” Here, we recount where this label originated and argue that the use of this label is at odds with the concept of “relevance” that has arisen in the contingent-capture literature. This is not merely a matter of labels, but a matter of inference: When people describe a flanker stimulus as being “task-irrelevant,” they may be (and sometimes are) tempted to infer that the conditions that were studied in the flanker task generalize to other tasks and other types of stimuli. Here, we show that this generalization is not warranted. The flanker effect exists not because attention has failed at selecting only the target from the display, but rather, the effect arises precisely because attention succeeded at selecting target-like (i.e., attentionally relevant) stimuli from the display. As a result, the flanker effect should not be used to infer how stimuli that are entirely unrelated to a participant’s main task would be processed. We propose the use of a new terminology to replace this potentially misleading label.     

The value of an oath of professional conduct: process, content, or both?

...I would suggest that the major objectives of studying the Hippocratic Oath or other pertinent oaths and codes are fourfold. First, studying oaths and codes pertaining to medical conduct and standards enables students to learn about historical changes and cultural influences. Second, choosing an oath or developing one for recitation at graduation enables students to engage in conceptual and moral reasoning. Third, the deliberations and discussions involving students enable them to practice interactional, communication skills about highly charged issues. Fourth, the identified limitations of the Hippocratic Oath or other pertinent oaths and codes enable students to appreciate the value of the broader principles that support medical ethics...The remainder of this commentary is divided into two parts. In the first part, recommendations for an educational program are presented. In the second part, recommendations for future research in this area are offered.     

The role of PKA, CaMKII, and PKC in avoidance conditioning: permissive or instructive?

This article explores the causal and correlative relationships between kinases and learning and memory. Specifically, the contributions of three kinases-protein kinase A (PKA), calcium calmodulin-dependent kinase II (CaMKII), and protein kinase C (PKC)-are assessed during the consolidation phase of avoidance conditioning. The following sources of evidence are considered: inhibitor data, activity monitoring, and transgenic studies. An exhaustive effort is made to address several issues regarding the participation of these kinases in (a) posttraining timing and magnitude, (b) location across many brain regions, and (c) the use of multiple pharmacological agents and assays. In addition, this article attempts to integrate the behavioral data with the purported role of kinases in long-term potentiation (LTP).     

One role or two? The function of psychological separation in role conflict

Student athletes vary in how much they view their academic and athletic role identities as separate from and interfering with each other. The authors investigated the relation of these perceptions to psychological well-being in 200 intercollegiate athletes. Measures included role separation, interference, identity, and well-being. Correlations indicated that interference related negatively to well-being, whereas viewing the roles as distinct related positively to well-being. Regression analyses of demographic and role identity variables also showed a positive association between role separation and well-being, and a significant Separation x Interference interaction. Specifically, role interference was negatively related to well-being for those who viewed the two roles as distinct but unrelated for those who did not. The buffering effects of role separation are discussed.     

The dilution effect: judgmental bias,conversational convention,or a bit of both?

This study explored competing normative interpretations of the dilution effect: the tendency for people to underutilize diagnostic evidence in prediction tasks when that evidence is accompanied by irrelevant information. From the normative vantage point of the intuitive statistician, the dilution effect is a judgmental bias that arises from the representativeness heuristic (similarity-matching of causes and effects). From the normative prospective of the intuitive politician, however, the dilution effect is a rational response to evidence presented in a setting in which Gricean norms of conversation are assumed to hold. The current experiment factorially manipulated conversational norms, the degree to which diagnostic evidence was diluted by irrelevant evidence, and the accountability of subjects for their judgments. Accountable subjects demonstrated a robust dilution effect when conversational norms were explicitly primed as well as in the no-priming control condition, but no dilution when conversational norms were explicitly deactivated. Non-accountable subjects demonstrated the dilution effect across norm activation conditions, with the strongest effect under the activation of conversational norms. Although the results generally support the conversational-norm interpretation of dilution, the significant dilution effect among non-accountable subjects in the norm-deactivated condition is more consistent with the judgmental-bias interpretation.     

The influence of making judgments of learning on memory performance: Positive,negative, or both?

Psychonomic Bulletin & Review - A common measure of memory monitoring——judgments of learning (JOLs)——has recently been shown to have reactive effects on learning. When...     

The role of attentional biases in PTSD: is it interference or facilitation?

Although attentional biases have been demonstrated in individuals with posttraumatic stress disorder (PTSD), the cognitive methodologies used have not allowed for disambiguation of two types of attentional biases. It remains unclear if PTSD involves difficulty disengaging attention from threatening stimuli (interference) or facilitated detection. To differentiate between attentional interference and facilitation, 57 male Vietnam-era veterans (30 High PTSD and 27 Low PTSD) completed a visual search task with a lexical decision component. High PTSD veterans who engaged in the interference task first showed increased interference to threat-relevant words relative to Low PTSD veterans. However, no evidence was found for facilitated detection of threatening stimuli in PTSD.     

The suppression role of positive affect on students’ science achievement in East Asia: the example of Taipei

This study focuses on “high achievement but low motivation” phenomenon that is prevalent in East Asian countries and districts, and uses eighth graders in Taipei that participated in TIMSS 2007 as an example to examine the direct and indirect effects of academic motivation, positive affect, and instruction on science achievement. Confirmatory Factor Analysis and Structural Equation Modeling were employed to test measurement and structural models and indicated a good fit of the models to the data. The results showed that expectancy and value in science and inquiry-based instruction are three significant and positive predictors of students’ positive affect toward science. In addition, expectancy, positive affect, and three types of instruction all significantly predicted students’ science achievement after the number of books at home and mother’s education were controlled. However, inquiry-based and practice-based instructions were negative predictors whereas traditional instruction was positive. The suppression role of the positive affect was partially supported between academic motivation and science achievement.     

The list-strength effect: Strength-dependent competition or suppression?

If several items are associated with a common cue, the cued recall of an item is often supposed to decrease as a function of the increase in strength of its competitors' associations with the cue. Evidence for such a list-strength effect has been found in prior research, but this effect could have been caused both by the strength manipulations and by retrieval-based suppression, because the strengthening and the output order of the items were confounded. The experiment reported here employed categorizable item lists; some categories in each list contained strong items only, some contained weak items only, and some contained both strong and weak items. Strengthening was accomplished by varying the exposure time of the items. The testing sequence of the items from each category was controlled by the use of category-plus-first-letter cues. When the typical confounding of strengthening and output order was mimicked, list-strength effects were found, which is consistent with prior research. However, when this confounding was eliminated, the list-strength effects disappeared: The recall of neither strong nor weak items varied with the strengths of the other category exemplars. This pattern of results indicates that the list-strength effect is not the result of strength-dependent competition, but is caused by output-order biases and a process of suppression.     

The role of the face in human emotion: first system or one of many?

Evidence relating to the hypothesis on facial feedback which ties the experience of discrete emotions to feedback from innately patterned facial expressions is discussed. Strong evidence is deduced for a more general form of the hypothesis, but the requirements of necessity and sufficiency representing the strictest form are only satisfied within narrow limits of experimental manipulations which are not common to all investigations. Evidence is deemed to support a relationship between facial expression and emotion, but facial expression is regarded as one of many systems and cannot be assigned an exclusive role (either as first system or as necessary system).     

Out with the old? The role of selective attention in retaining targets in partial report

In the partial-report task, subjects are asked to report only a portion of the items presented. Selective attention chooses which objects to represent in short-term memory (STM) on the basis of their relevance. Because STM is limited in capacity, one must sometimes choose which objects are removed from memory in light of new relevant information. We tested the hypothesis that the choices among newly presented information and old information in STM involve the same process—that both are acts of selective attention. We tested this hypothesis using a two-display partial-report procedure. In this procedure, subjects had to select and retain relevant letters (targets) from two sequentially presented displays. If selection in perception and retention in STM are the same process, then irrelevant letters (distractors) in the second display, which demanded attention because of their similarity to the targets, should have decreased target report from the first display. This effect was not obtained in any of four experiments. Thus, choosing objects to keep in STM is not the same process as choosing new objects to bring into STM.     

Repetition blindness: out of sight or out of mind?

Does repetition blindness represent a failure of perception or of memory? In Experiment 1, participants viewed rapid serial visual presentation (RSVP) sentences. When critical words (C1 and C2) were orthographically similar, C2 was frequently omitted from serial report; however, repetition priming for C2 on a postsentence lexical decision task was equivalent whether or not C1 was similar to C2. In Experiment 2, participants monitored RSVP sentences for a predetermined target. Participants frequently failed to detect the target when it was preceded by an orthographically similar word. In Experiment 3, the authors investigated the role of the attentional blink in this effect. These experiments suggest that repetition blindness is a failure of conscious perception, consistent with predictions of the token-individuation hypothesis.     

Intergenerational occupational transmission: Do offspring walk in the footsteps of mom or dad,or both?

The purpose of this research was to apply the Theory of Planned Behavior (TPB) in order to investigate intergenerational occupational transmission between parents and their children. A sample of 260 undergraduate students completed a questionnaire measuring TPB variables, and congruence was calculated between the parents' occupations and their offspring's chosen profession. Intention to work in the parents' occupations was predicted by attitude, subjective norm and perceived behavioral control. Congruence between parents' and their children's occupational choice was predicted by intention and perceived behavioral control. The findings provide support to the relational approach in career choice. Implications of the findings for career counselors and young people's career choices are discussed.     

The impact of relational demographics on perceived managerial trustworthiness: similarity or norms?

Perceived trustworthiness is a critical antecedent of interpersonal trust, yet researchers have a limited understanding of how such perceptions are generated. The authors used 2 competing perspectives within the relational demography literature--similarity-attraction and relational norms--to empirically examine the effect of demographic differences. Whereas the similarity-attraction account suggests that subordinates will perceive their managers as more trustworthy when managers and staff are similar in demographic attributes, the relational norms account proposes that subordinates will perceive their managers as more trustworthy when their demographic differences follow normative expectations. Data collected from a field study of 178 manager-subordinate dyads in Hong Kong and Macau support the relational norms account in terms of education and organizational rank. The authors discuss the theoretical and practical implications of the study.

The director task: A test of Theory-of-Mind use or selective attention?

Over two decades, the director task has increasingly been employed as a test of the use of Theory of Mind in communication, first in psycholinguistics and more recently in social cognition research. A new version of this task was designed to test two independent hypotheses. First, optimal performance in the director task, as established by the standard metrics of interference, is possible by using selective attention alone, and not necessarily Theory of Mind. Second, pragmatic measures of Theory-of-Mind use can reveal that people actively represent the director’s mental states, contrary to recent claims that they only use domain-general cognitive processes to perform this task. The results of this study support both hypotheses and provide a new interactive paradigm to reliably test Theory-of-Mind use in referential communication.
