How prioritized is self-prioritization during stimulus processing?

Recent research has suggested that self-relevance automatically enhances stimulus processing (i.e., the self-prioritization effect). Notably, information associated with one’s self elicits faster responses than comparable material associated with other targets (e.g., friend, stranger). Challenging the assertion that self-prioritization is an obligatory process, here we hypothesized that self-relevance only facilitates performance when task sets draw attention to previously formed target-object associations. The results of two experiments were consistent with this viewpoint. Compared with arbitrary objects owned by a friend, those owned by the self were classified more rapidly when participants were required to report either the owner or identity of the items (i.e., semantic task set). In contrast, self-relevance failed to facilitate performance when participants judged the orientation of the stimuli (i.e., perceptual task set). These findings demonstrate the conditional automaticity of self-prioritization during stimulus processing.     

Target self-relevance speeds visual search responses but does not improve search efficiency

ABSTRACT

In a variety of contexts, arbitrarily associating one’s self with a stimulus improves performance relative to stimuli that are not self-associated, implying enhanced processing of self-associated stimuli (“self-relevance” effects). Self-relevance has been proposed to influence diverse aspects of cognition, including the perceptual prioritization of self-relevant stimuli (“self-prioritization” effects). We sought to elucidate the mechanisms of self-prioritization by using a visual search paradigm. In three experiments, subjects learned two stimulus-label combinations (SELF and OTHER), and then searched for one of those stimuli (cued by the label) on each trial, with a variable number of distractors present on each trial. We hypothesized that, if self-relevance enhances the perceptual salience of the stimuli pre-attentively, then the self-relevance of a target should result in improved search efficiency. In three experiments using conjunction-defined (Experiments 1–2) and feature-defined (Experiment 3) targets, we found that self-relevant targets were associated with overall faster responses than non-self-relevant targets (an intercept effect). However, the slopes of the search size by reaction time (RT) function were never significantly different between the self-relevant and non-self-relevant conditions, counter to the hypothesis that self-prioritization is pre-attentive. These results constitute novel evidence that self-relevance affects visual search performance, but they also cast doubt on the possibility that self-relevance enhances the perceptual salience of a target in a manner similar to physical manipulations. We propose that the self-relevance of a stimulus alters processing only after the self-relevant item has been attended.     

Self-prioritization and perceptual matching: The effects of temporal construal

Recent research has revealed that self-referential processing enhances perceptual judgments — the so-called self-prioritization effect. The extent and origin of this effect remains unknown, however. Noting the multifaceted nature of the self, here we hypothesized that temporal influences on self-construal (i.e., past/future-self continuity) may serve as an important determinant of stimulus prioritization. Specifically, as representations of the self increase in abstraction as a function of temporal distance (i.e., distance from now), self-prioritization may only emerge when stimuli are associated with the current self. The results of three experiments supported this prediction. Self-relevance only enhanced performance in a standard perceptual-matching task when stimuli (i.e., geometric shapes) were connected with the current self; representations of the self in the future (Expts. 1 & 2) and past (Expt. 3) failed to facilitate decision making. To identify the processes underlying task performance, data were interrogated using a hierarchical drift diffusion model (HDDM) approach. Results of these analyses revealed that self-prioritization was underpinned by a stimulus bias (i.e., rate of information uptake). Collectively, these findings elucidate when and how self-relevance influences decisional processing.     

Obstructing the cascade: motivational system coactivation dampening defensive reactions to threat and disgust

ABSTRACT

This study uses the limited capacity model of motivated mediated message processing (LC4MP; Lang, 2006) as a framework to study coactivation of fundamental motivational systems elicited by common message features in antismoking public service announcements (PSAs): the appetitive system (elicited by smoking cues) and aversive system (elicited by perceived threat and disgust). Specific predictions were made for smoking cues’ ability to provide cognitive resources for message encoding when simultaneous message elements are so highly aversive they begin to deplete resources (i.e., during a defensive cascade). The results showed that greater resources were expended on encoding headlines as indicated by increased attention (i.e., gaze duration and frequency of fixation) and better free recall, but not noncue pictorial elements when smoking cues were present in PSAs high in perceived disgust. Although the inclusion of smoking cues was effective in highly aversive PSAs, results indicated that the inclusion of smoking cues reduced attention and free recall for moderately and low-aversive PSAs. Theoretical advances include the use of motivational coactivation to reduce defensive reactions and the differential allocation impact on text versus visual message elements. Applied implications highlight the importance of formative production research to ensure aversive activation is high enough to offset urges associated with smoking cues.     

Cue self-relevance affects autobiographical memory specificity in individuals with a history of major depression

Previously depressed and never-depressed individuals identified personal characteristics (self-guides) defining their ideal, ought, and feared selves. One week later they completed the autobiographical memory test (AMT). For each participant the number of AMT cues that reflected self-guide content was determined to produce an index of AMT cue self-relevance. Individuals who had never been depressed showed no significant relationship between cue self-relevance and specificity. In contrast, in previously depressed participants there was a highly significant negative correlation between cue self-relevance and specificity--the greater the number of AMT cues that reflected self-guide content, the fewer specific memories participants recalled. It is suggested that in individuals with a history of depression, cues reflecting self-guide content are more likely to prompt a shift to processing of information within the long-term self (Conway, Singer, & Tagini, 2004), increasing the likelihood that self-related semantic information will be provided in response to cues on the autobiographical memory test.     

P300 as an index of attention to self-relevant stimuli

Past work suggests that information related to the self receives ‘preferential access’ to the limited pool of attentional resources. However, these studies have been limited by their reliance on response-time measures, which require overt responding and represent the combined effects of multiple stages of information processing. One aim of the present study was to extend past work by obtaining a response-independent index of attention allocation sensitive to changes in discrete stages of information processing. An additional goal was to explore the potential time course of differential sensitivity to self-relevant cues. We assessed the P300, an ERP component that provides an index of attentional resources, evoked by autobiographical self-relevant stimuli (e.g., one’s own name). As expected, P300 was augmented for self-relevant stimuli relative to control stimuli. In addition, analyses of P300 latency indicate that the effects of self-relevance are present during higher-order stages of cognitive processing related to selective attention. These results complement and extend previous work on the role of self-relevance in the selection of material for further processing.     

The next trial will be conflicting! Effects of explicit congruency pre-cues on cognitive control

The dual mechanisms of control account proposed a role for proactive and reactive mechanisms in minimizing or resolving interference in conflict tasks. Proactive mechanisms are activated in advance of stimulus onset and lead to preparatory biasing of attention in a goal-directed fashion. Reactive mechanisms are triggered post-stimulus onset. Using an explicit, trial-by-trial pre-cueing procedure in a 4-choice color-word Stroop task, we investigated effects of congruency pre-cues on cognitive control. Under conditions of stimulus uncertainty (i.e., each word was associated with multiple, equally probable responses), pre-cue benefits were observed on incongruent trials when cues were 100 % valid but not when they were 75 % valid. These benefits were selectively found at the longest cue-to-stimulus interval (2,000 ms), consistent with a preparation-dependent proactive control mechanism. By contrast, when a reactive strategy of switching attention to the irrelevant dimension to predict the single correlated response was viable, pre-cue benefits were observed on incongruent trials for all cue-to-stimulus intervals including the shortest that afforded only 500 ms to prepare. The findings (a) suggest a restricted role for the preparation-dependent biasing of attention via proactive control in response to explicit, trial-by-trial pre-cues while (b) highlighting strategies that lead to pre-cue benefits but which appear to reflect primarily reactive use of the information afforded by the pre-cues. We conclude that pre-cues, though available in advance of stimulus onset, may stimulate proactive or reactive minimization of interference.     

Quantity discrimination in fish species: fish use non-numerical continuous quantity traits to select shoals

Fish typically prefer to live in big shoals due to the associated ecological benefits. Shoaling is a behavior that depends on the ability to quantitatively discriminate. The fundamental mechanism involved in quantity discrimination determines whether fish can discriminate a shoal using numerical discrete cues (e.g., number of shoal members), non-numerical continuous traits (e.g., total body surface area) or both; however, the mechanism is currently a controversial topic. In the present study, we used a spontaneous choice experiment to test whether guppy (Poecilia reticulata), zebrafish (Danio rerio), Chinese crucian carp (Carassius auratus) and qingbo (Spinibarbus sinensis) rely on continuous (i.e., body surface area) or discrete (i.e., number of shoal members) information for shoal selection by altering the body surface area (cumulative body surface area ratio of 3:2 or 1:1) between two stimulus shoals with a different number of members (2 individuals vs 3 individuals). All four fish species preferred to shoal with the stimulus shoal with the larger cumulative surface area even if the shoal had fewer members; however, fish showed no shoal preference when the cumulative surface body areas of both stimulus shoals were equal. Furthermore, qingbo did not numerically discriminate between a shoal with 1 individual and a shoal with 3 individuals when the cumulative surface areas of both stimulus shoals were equal; however, qingbo showed a preference for the shoal with the larger cumulative surface area when the two stimulus shoals each had 3 individuals. In conclusion, the present study demonstrated that all four fish species relied only on non-numerical continuous quantity information for shoal selection, at least under a difficult task (i.e., 2 vs 3).     

Configural coding of facial expressions: The impact of inversion and photographic negative

In previous research we used the composite paradigm (Young, Hellawell, & Hay, ) to demonstrate that configural cues are important for interpreting facial expressions. However, different configural cues in face perception have been identified, including holistic processing (i.e., perception of facial features as a single gestalt) and second‐order spatial relations (i.e., the spatial relationship between individual features). Previous research has suggested that the composite effect for facial identity operates at the level of holistic encoding. Here we show that the composite effect for facial expression has a similar perceptual basis by using different graphic manipulations (stimulus inversion and photographic negative) in conjunction with the composite paradigm. In relation to Bruce and Young's () functional model of face recognition, a suitable level for the composite effect is a stage of front‐end processing referred to as structural encoding, that is common to both facial identity and facial expression perception.     

Self-Relevance of Performance, Task Difficulty, and Task Engagement Assessed as Cardiovascular Response

Two experiments examined task engagement, quantified as cardiovascular (CV) response, under conditions of high self-relevance of performance (i. e., when performance had strong implications for the individual's self-definition and self-esteem). Experiment 1 involved a 2 (self-relevance) × 2 (task difficulty) design and revealed, in accordance with predictions derived from Brehm's energization model, that self-relevance per se does not result in high engagement, but that high self-relevance bound up with high task difficulty does. Experiment 2 involved three difficulty conditions (very easy, moderate, very difficult) under highly self-relevant performance conditions and revealed a curvilinear difficulty/engagement relationship. In both studies CV responses were independent of feeling states.     

Action-related objects influence the distribution of visuospatial attention

Previous studies have shown that attention is drawn to the location of manipulable objects and is distributed across pairs of objects that are positioned for action. Here, we investigate whether central, action-related objects can cue attention to peripheral targets. Experiment 1 compared the effect of uninformative arrow and object cues on a letter discrimination task. Arrow cues led to spatial-cueing benefits across a range of stimulus onset asynchronies (SOAs: 0 ms, 120 ms, 400 ms), but object-cueing benefits were slow to build and were only significant at the 400-ms SOA. Similar results were found in Experiment 2, in which the targets were objects that could be either congruent or incongruent with the cue (e.g., screwdriver and screw versus screwdriver and glass). Cueing benefits were not influenced by the congruence between the cue and target, suggesting that the cueing effects reflected the action implied by the central object, not the interaction between the objects. For Experiment 3 participants decided whether the cue and target objects were related. Here, the interaction between congruent (but not incongruent) targets led to significant cueing/positioning benefits at all three SOAs. Reduced cueing benefits were obtained in all three experiments when the object cue did not portray a legitimate action (e.g., a bottle pointing towards an upper location, since a bottle cannot pour upwards), suggesting that it is the perceived action that is critical, rather than the structural properties of individual objects. The data suggest that affordance for action modulates the allocation of visual attention.     

Inhibition of return and attentional control settings

In the present study, we used a spatial cuing paradigm in conjunction with a choice identification task to investigate whether exogenous attentional orienting and inhibition of return are affected by attentional control settings. As in previous studies (e.g., Folk, Remington, & Johnston, 1992), onset- and color-defined targets were crossed with uninformative onset- and color-defined cues. As expected, when the cue-target stimulus onset asynchrony (SOA) was short (i.e., 100 msec), the results showed that exogenous attentional orienting was contingent on attentional set; attentional capture occurred in response to a particular cue only when the feature that defined the cue also defined the target (Folk et al., 1992). More importantly, when the cue-target SOA was long (i.e., 1,000 msec), the results showed that the occurrence of inhibition of return was also contingent on attentional set, at least partially so; inhibition of return occurred in response to onset cues only when they preceded onset targets. In contrast, inhibition of return never occurred in response to color cues (at a variety of long SOAs). The associations and dissociations that were observed between exogenous attentional orienting and inhibition of return are discussed in terms of posterior and anterior attention networks in the brain (Posner & Petersen, 1990).     

Precueing spatial S-R correspondence: is there regulation of expected response conflict?

Four experiments investigated the ability to prepare for the level of forthcoming stimulus-response correspondence in choice-response tasks. In a Simon task, participants responded to the color of spatially variable stimuli with spatially variable responses. Participants were given advance information about whether a forthcoming stimulus-response event would be spatially corresponding, neutral, or spatially noncorresponding. Reliable cues decreased reaction times (RTs) in the corresponding conditions of 2- and 3-choice tasks, decreased RTs in noncorresponding conditions of a 2-choice task but not in a 3-choice task, and left RTs in neutral conditions unaffected. The pattern of results suggests that participants used reliable cues for responding to the nominally irrelevant stimulus location if the correct response could be inferred from location (attention switching). By contrast, the lack of cueing effects on performance in noncorresponding conditions of 3-choice tasks suggests that participants cannot use cues for changing the attentional weights of processing channels for different stimulus dimensions (gating). In summary, gating may be involved in the regulation of experienced response conflict, but the present results suggest that it is not involved in the regulation of expected (i.e., predicted) response conflict.     

Skill differences in visual anticipation of type of throw in team-handball penalties

ObjectivesVisual identification and anticipation of an opponent's action intentions is crucial for successful performance in interactive situations such as team-handball penalties. We conducted two experiments to examine experienced and novice team-handball goalkeepers' ability to predict the type of throw in handball penalties and to identify the observers' reliance on local versus globally distributed spatial cues.Design and methodsIn Experiment 1, following a 2 (Skill) × 5 (Temporal Occlusion Condition) factorial design participants were provided with videos of team-handball penalties where the amount of viewing time was varied. In Experiment 2, another sample of experienced and novice goalkeepers watched videos of spatially manipulated penalties where specific parts of the thrower's body or the ball were either removed or presented in isolation (2 [Skill] × 9 [Display Condition] factorial design).ResultsIn Experiment 1, experienced goalkeepers outperformed novices and both groups similarly improved their performances with later occlusion conditions. In Experiment 2, experienced goalkeepers were again superior to novices, and local cues (e.g., ball and hand) were sufficient for better than chance predictions in both groups. Moreover, experienced in contrast to novice goalkeepers (i) suffered from the removal of and (ii) benefited from the addition of distal (i.e., throwing arm and ball) as well as proximal (i.e., upper body) kinematic features.ConclusionsOur research is in line with previous findings on perceptual-cognitive expertise in sports and suggests that experienced team-handball goalkeepers rely on multiple, globally distributed cues when making anticipatory judgments.     

Colour-cueing in visual search

Several studies have shown that people can selectively attend to stimulus colour, e.g., in visual search, and that preknowledge of a target colour can improve response speed/accuracy. The purpose was to use a form-identification task to determine whether valid colour precues can produce benefits and invalid cues costs. The subject had to identify the orientation of a "T"-shaped element in a ring of randomly-oriented "L"s when either two or four of the elements were differently coloured. Contrary to Moore and Egeth's (1998) recent findings, colour-based attention did affect performance under data-limited conditions: Colour cues produced benefits when processing load was high; when the load was reduced, they incurred only costs. Surprisingly, a valid colour cue succeeded in improving performance in the high-load condition even when its validity was reduced to the chance level. Overall, the results suggest that knowledge of a target colour does not facilitate the processing of the target, but makes it possible to prioritize it.     

Reinstatement of odour context cues veridical memories but not false memories

ABSTRACT

The sense of smell has made a recent return to the forefront of research on episodic memory. Odour context cues can reactivate recently encoded memories during sleep-dependent memory consolidation [e.g., Rasch, B., Buchel, C., Gais, S., & Born, J. (2007). Odor cues during slow-wave sleep prompt declarative memory consolidation. Science, 315, 1426–1429], and reinstating the odour experienced during encoding at test results in superior recall and recognition [e.g., Isarida, T., Sakai, T., Kubota, T., Koga, M., Katayama, Y., & Isarida, T. K. (2014). Odor-context effects in free recall after a short retention interval: A new methodology for controlling adaptation. Memory & Cognition, 42, 421–433]. However, whether the impact of odour cues is restricted to the specific memories studied in the presence of the odour, or whether reinstating the odour also cues unstudied memories that are semantically related to the studied memories (i.e., false memories) is unknown. We used the Deese-Roediger-McDermott false memory paradigm to quantify the impact of odour cues on both veridical memory and false memory. Reinstating the odour presented during the study of the DRM word lists at the test phase resulted in better free recall of the studied words, but had no statistically significant impact on the number of false memories produced. We argue that odour cues influence recall of the memories they co-occurred with during study but potentially not semantically related memories.     

Test anxiety and ego-threatening stress: Over- (and under-) estimation of emotional reactivity

Abstract

This study examined discrepancies between subjective and objective measures of state anxiety as a function of test anxiety in undergraduates. Under evaluative stress conditions, state anxiety was assessed in terms of (a) self-reported cognitive and somatic anxiety, (b) behavioral reactivity (motor and facial tension, avoidance comments and avoidance of eye contact), (c) physiological arousal (heart rate and skin resistance), and (d) cognitive and motor task performance. Participants high in test anxiety showed disproportionately greater self-reported than objective state anxiety. In contrast, those low in test anxiety showed lower self-reported than objective anxiety. The high- and the low-test-anxiety groups differed only in self-reported emotional reactivity. In line with current cognitive theories of anxiety, overestimation of reactivity in high-test anxiety, as well as underestimation in low-test anxiety, are conceptualized as a hypervigilance bias and an avoidance bias, respectively, in processing internal cues, i.e., prioritization and inhibition of attention to one's own behavioral and physiological signs of distress.     

Adult age differences in strategic and dynamic components of focusing visual attention

Abstract

Changes in the width of a focally attended area were assessed by analysis of changes in reaction time associated with response-incompatible nontarget letters (flankers). In two experiments, the focus of attention widened as an increasing function of stimulus onset asynchrony (SOA). In contrast to the predictions of generalized slowing and inhibition-deficit models, this dynamic change in attention was comparable for young and older adults in both experiments. Evidence accumulation outside the focus of attention was greater for young adults than for older adults when target location varied (Experiment 2). This latter effect, however, was strategic (i.e., independent of SOA). Analyses of the task complexity functions (Brinley plots) indicated a greater contribution of generalized slowing when target location was constant (Experiment 1) than when location varied (Experiment 2).     

Visually induced gains in pitch discrimination: Linking audio-visual processing with auditory abilities

Perception is fundamentally a multisensory experience. The principle of inverse effectiveness (PoIE) states how the multisensory gain is maximal when responses to the unisensory constituents of the stimuli are weak. It is one of the basic principles underlying multisensory processing of spatiotemporally corresponding crossmodal stimuli that are well established at behavioral as well as neural levels. It is not yet clear, however, how modality-specific stimulus features influence discrimination of subtle changes in a crossmodally corresponding feature belonging to another modality. Here, we tested the hypothesis that reliance on visual cues to pitch discrimination follow the PoIE at the interindividual level (i.e., varies with varying levels of auditory-only pitch discrimination abilities). Using an oddball pitch discrimination task, we measured the effect of varying visually perceived vertical position in participants exhibiting a wide range of pitch discrimination abilities (i.e., musicians and nonmusicians). Visual cues significantly enhanced pitch discrimination as measured by the sensitivity index d’, and more so in the crossmodally congruent than incongruent condition. The magnitude of gain caused by compatible visual cues was associated with individual pitch discrimination thresholds, as predicted by the PoIE. This was not the case for the magnitude of the congruence effect, which was unrelated to individual pitch discrimination thresholds, indicating that the pitch-height association is robust to variations in auditory skills. Our findings shed light on individual differences in multisensory processing by suggesting that relevant multisensory information that crucially aids some perceivers’ performance may be of less importance to others, depending on their unisensory abilities.     

Extending a focused attention paradigm to critically test for unconscious congruency effects

ABSTRACT

In a novel integration of research designs, we tested for unconscious perception effects at an unattended stimulus location using a focused attention paradigm (Lachter, J., Forster, K. I., & Ruthruff, E. 2004. Forty-five years after Broadbent (1958): Still no identification without attention. Psychological Review, 111(4), 880–913. https://doi.org/10.1037/0033-295X.111.4.880). Target-masked word or nonword prime stimuli were briefly displayed for 14, 28, or 56?ms at an experimentally-defined attended or unattended location, followed by a lexical decision task. At the briefest prime durations (14 and 28?ms), we failed to find any evidence for unattended priming effects, consistent with Lachter et al., but there were some small priming (i.e., congruency) effects at the attended location. The 14?ms primes could not be discriminated above chance, but could be detected. Our results support the claim that perceptual processing is strongest with focal attention. For the 14?ms primes at the attended location, results could support an unconscious perception claim, but the effect was weak and awareness of the primes was unlikely to have been completely eliminated.
