Audiovisual semantic interference and attention: Evidence from the attentional blink paradigm

In the present study we investigate the role of attention in audiovisual semantic interference, by using an attentional blink paradigm. Participants were asked to make an unspeeded response to the identity of a visual target letter. This target letter was preceded at various SOAs by a synchronized audiovisual letter-pair, which was either congruent (e.g. hearing an “F” and viewing an “F”) or incongruent (e.g. hearing an “F” and viewing a “Z”). In Experiment 1, participants were asked to match the members of the audiovisual letter-pair. In Experiment 2, participants were asked to ignore the synchronized audiovisual letter-pairs altogether and only report the visual target. In Experiment 3, participants were asked to identify only one of the audiovisual letters (identify the auditory letter, and ignore the synchronized visual letter, or vice versa). An attentional blink was found in all three experiments indicating that the audiovisual letter-pairs were processed. However, a congruency effect on subsequent target detection was observed in Experiments 1 and 3, but not in Experiment 2. The results indicate that attention to the semantic contents of at least one modality is necessary to establish audiovisual semantic interference.     

Exploring the impact of social judgeability concerns on the interplay of associative and deliberative attitude processes

Some recent research applying dual-systems logic suggests that different attitude measures reflect independent modes of evaluation with explicit measures primarily affected by deliberative processes and implicit measures primarily affected by automatic processes. In the current work we hypothesized that explicit attitude measures often do not reflect the outcome of automatic or associative processing because social judgeability concerns prevent people from reporting consciously inexplicable “gut feelings” towards the attitude object. To explore this possibility, we simultaneously presented participants with associative and deliberative information about a target person and manipulated their sensitivity to social judgeability concerns with different sets of task instructions. Although an explicit attitude measure was unaffected by subliminally presented associative information following a standard instruction set, this content did impact explicit judgments when social judgeability concerns were assuaged with a “go with your gut” instruction set.     

Spatial cueing in time–space synesthetes: An event-related brain potential study

Some people report that they consistently and involuntarily associate time events, such as months of the year, with specific spatial locations; a condition referred to as time–space synesthesia. The present study investigated the manner in which such synesthetic time–space associations affect visuo-spatial attention via an endogenous cuing paradigm. Reaction times and ERPs were recorded as 12 time–space synesthetes and 12 control participants did a peripheral target detection task, cued by three different types of centrally presented cues: arrows pointing left or right, direction words “left” or “right”, and month names associated with either the left or the right side of the synesthete’s mental calendar (e.g., “October” or “May”). Cues were followed by probes on the left or right side of the screen, and participants responded to the probes with button presses. Behavioral and ERP data suggested that for synesthetes, month words functioned more effectively as cues to direct attention in space. In synesthetes but not controls, a comparison of ERPs to probes cued by months revealed effects of cue validity on the P3b component peaking 370 ms post-onset and on the subsequent positive slow wave (pSW) observed 600–900 ms post-onset (both larger for invalid probes). No effects of cue validity were observed on early visual potentials (N1) for probes cued by months. The findings suggest that in these time–space synesthetes cue validity influenced post-perceptual processes, such as stimulus evaluation and categorization, with no evidence for enhanced visual processing.     

Taking from those that have more and giving to those that have less: How inequity frames affect corrections for inequity

Most theories of inequity focus on relative inequity. In contrast, this paper provides evidence that individuals infer what people should have (i.e. an absolute standard) from the way inequity is described. In the reported experiment, participants give more to a subordinate actor when inequity is described in terms of “less than” rather than “more than,” and take more from a dominant actor when inequity is described in terms of “more than” rather than “less than,” even though the magnitude of inequity is constant. Mediational analyses suggest that these differences are driven by changes in individuals’ perceptions of what the actors should have (i.e. the standard). We conclude by discussing the implications for motivated perceptions of inequity and redistributive policy attitudes.

Tag, you're it: Tagging as an alternative to yes/no recognition in item method directed forgetting

The current study contrasted a standard yes/no recognition task with a tagging recognition task in the context of an item-method directed forgetting paradigm. During the study phase, a series of words was presented one at a time, each followed by an instruction to remember (R) or forget (F). The retention of R and F study words was tested using either a typical yes/no recognition task or a tagging recognition task in which participants labeled each word as “R”, “F” or “New”. The directed forgetting effect observed in each task was equivalent in magnitude. However, the tagging recognition task afforded an additional analysis of the errors of misattribution that was not possible with the more typical yes/no recognition task. Interestingly, when falsely recognizing a Foil word, participants were more likely to assign an “F” tag than an “R” tag. These errors of misattribution are consistent with existing accounts of directed forgetting that suggest R words are better encoded than F words. We argue for the utility of the tagging procedure, given it does not alter the directed forgetting effect normally seen with yes/no recognition but provides additional information about errors of misattribution.     

The paradox of moral focus

When we evaluate moral agents, we consider many factors, including whether the agent acted freely, or under duress or coercion. In turn, moral evaluations have been shown to influence our (non-moral) evaluations of these same factors. For example, when we judge an agent to have acted immorally, we are subsequently more likely to judge the agent to have acted freely, not under force. Here, we investigate the cognitive signatures of this effect in interpersonal situations, in which one agent (“forcer”) forces another agent (“forcee”) to act either immorally or morally. The structure of this relationship allowed us to ask questions about both the “forcer” and the “forcee.” Paradoxically, participants judged that the “forcer” forced the “forcee” to act immorally (i.e. X forced Y), but that the “forcee” was not forced to act immorally (i.e. Y was not forced by X). This pattern obtained only for human agents who acted intentionally. Directly changing participants’ focus from one agent to another (forcer versus forcee) also changed the target of moral evaluation and therefore force attributions. The full pattern of judgments may provide a window into motivated moral reasoning and focusing bias more generally; participants may have been motivated to attribute greater force to the immoral forcer and greater freedom to the immoral forcee.     

Functions of attitudes towards ethnic groups: Effects of level of abstraction

A direct measure of attitude function was used to examine symbolic and instrumental elements of racial attitudes as a function of level of abstraction. Two studies were conducted in different countries, in which participants explained their thoughts and feelings concerning a specific (e.g., “Indians” or “Chinese”) or abstract (e.g., “Ethnic Minorities”) attitude object, and then rated the importance of each thought or feeling. A coding scheme was used to record the attitude function represented by each thought or feeling. In both studies, symbolic functions were more present for the abstract target than the specific targets. These differences have important implications for interventions and theories that address prejudice. They also provide evidence that functions of attitudes towards broader social groups cannot be regarded as the central tendency of functions toward subgroups, which is an important potential caveat to theories of social categorization.     

A preference for genuine smiles following social exclusion

Research indicates that rejected individuals are better than others at discriminating between genuine (Duchenne) and deceptive (non-Duchenne) smiles (i.e., true versus false signals of affiliative opportunity). We hypothesized that rejected individuals would show a greater preference to work with individuals displaying Duchenne versus non-Duchenne smiles. To test this, participants wrote essays about experiences of inclusion, exclusion, or mundane events. They then saw a series of 20 videos of smiling individuals (10 with Duchenne and 10 with non-Duchenne smiles). Participants then indicated how much they would like to work with each target. Analyses revealed that compared to included and control participants, excluded individuals showed a greater preference to work with individuals displaying “real” as opposed to “fake” smiles. This effect was partially mediated by threats to “relational needs” (Williams, 2007) and fully mediated by threats to self-esteem. These results suggest that exclusion yields adaptive responses that could facilitate reconnection with others.     

Social desirability, personality questionnaires, and the “better than average” effect

It is well established that respondents are much more likely to rate themselves highly on personality questionnaire items with high social desirability (SD) than on items with low SD. However, conflicting explanations have been offered for this phenomenon. In the present study, 286 participants were randomly assigned to four groups that rated 119 items from two well-known personality questionnaires. One group of participants rated themselves, a second group rated their family and friends, a third rated “people in general,” and a fourth rated the items’ SD. It was found that mean SD ratings of personality items were highly correlated with mean self-ratings and with mean ratings of family and friends for the same items (all rs > .800), but not with mean ratings of “people in general.” In other words, participants strongly tended to rate themselves, their family, and their friends as high on socially desirable qualities, but this tendency did not extend to ratings of people in general. These results support the conclusion that respondents’ personality ratings of themselves, their family and friends, but not of people in general, are influenced by the form of self-serving bias known as the “better than average effect.”     

When women can’t do math: The interplay of self-construal, group identification, and stereotypic performance standards

The present research examined the interplay of self-construal (independent vs. interdependent), gender group identification, and performance standards (positive vs. negative) on women’s math performance. Female participants were given a subtle self-prime prior to completing a math test under conditions where either a positive or negative group-based performance standard was rendered accessible. We report an interactive effect of self-construal, gender identification, and performance standard such that a negative (compared to a positive) standard decreased performance under interdependent self-prime (“we”) conditions, whereas the reverse pattern emerged under independent self-prime (“I”) conditions. Importantly, we observed this interplay of performance standards and self-construal only in individuals who self-identify with their gender group whereas performance outcomes of low identifiers were not affected by the experimental manipulations.     

In search of the nonconscious sources of goal pursuit: Accessibility and positive affective valence of the goal state

Two experiments tested the hypothesis that the mere priming of the representation of a goal state motivates people to pursue this state to the extent that it is associated with positive affect. In Experiment 1, all participants completed an affective priming task in which the goal concept of “socializing” was primed and tested for positive valence. Subsequently, they were given an instrumental task which provided the opportunity to pursue that state. It was established that participants put more effort in the task to attain the primed goal state when the implicitly assessed affective valence of the state was more positive. Experiment 2 replicated and extended these effects by showing that a stronger association of the goal state with positive affect—as assessed by the EAST—led to more effort to attain the state, but only when “socializing” was primed.     

Effects of ownership expressed by the first-person possessive pronoun

The present study examined the behavioral effects of the first-person possessive pronoun. In each trial, a noun (e.g. cup or bread) was presented to participants after visual presentation of a possessive pronoun “wo de” (Chinese for “my”) or “ta de” (Chinese for “his”), which formed ownership. Half participants were assigned to contextual encoding (CE) condition in which they were required to judge whether they liked the item expressed by a noun from the first or third-person perspective. The rest were assigned to perceptual encoding (PE) condition in which they were asked to judge what color the noun was. A subsequent recall test was performed. The results showed that there were significant memory and response advantages for nouns in “my” ownership under both conditions. The results were discussed with reference to self-specificity and other effects in the current study.     

A left cerebral hemisphere’s superiority in processing spatial-categorical information in a non-verbal semantic format

It has been shown that the left and right cerebral hemispheres (LH and RH) respectively process qualitative or “categorical” spatial relations and metric or “coordinate” spatial relations. However, categorical spatial information could be thought as divided into two types: semantically-coded and visuospatially-coded categorical information. We examined whether a LH’s advantage in processing semantic-categorical information is observed in a non-verbal format, and also whether semantic- and visuospatial-categorical processing are differentially lateralized. We manipulated the colors and positions of the standard traffic light sign as semantic- and visuospatial-categorical information respectively, and tested performance with the divided visual field method. In the semantic-categorical matching task, in which the participants judged if the semantic-categorical information of a successive cue and target was the same, a right visual field advantage was observed, suggesting a LH’s preference for processing semantic-categorical information in a non-verbal format. In the visuospatial-categorical matching task, in which the participants judged if the visuospatial-categorical information of a successive cue and target was identical, a left visual field advantage was obtained. These results suggest that the processing of semantic-categorical information is lateralized in LH, and we discuss the dissociation between the two types of categorical information.     

High neuromagnetic activation in the left prefrontal and frontal cortices correlates with better memory performance for abstract words

The ability to store and manipulate online information may be enhanced by an inner speech mechanism that draws upon motor brain regions. Neural correlates of this mechanism were examined using event-related functional magnetic resonance imaging (fMRI). Sixteen participants completed two conditions of a verbal working memory task. In both conditions, participants viewed one or two target letters. In the “storage” condition, these targets were held in mind across a delay. Then a probe letter was presented, and participants indicated by button press whether the probe matched the targets. In the “manipulation” condition, participants identified new targets by thinking two alphabetical letters forward of each original target (e.g., f → h). Participants subsequently indicated whether the probe matched the newly derived targets. Brain activity during the storage and manipulation conditions was examined specifically during the delay phase in order to directly compare manipulation versus storage processes. Activations that were common to both conditions, yet disproportionately greater with manipulation, were observed in the left inferior frontal cortex, premotor cortex, and anterior insula, bilaterally in the parietal lobes and superior cerebellum, and in the right inferior cerebellum. This network shares substrates with overt speech and may represent an inner speech pathway that increases activity with greater working memory demands. Additionally, an inverse correlation was observed between manipulation-related brain activity (on correct trials) and test accuracy in the left premotor cortex, anterior insula, and bilateral superior cerebellum. This inverse relationship may represent intensification of inner speech as one struggles to maintain performance levels.     

Do you see what I’m singing? Visuospatial movement biases pitch perception

The nature of the connection between musical and spatial processing is controversial. While pitch may be described in spatial terms such as “high” or “low”, it is unclear whether pitch and space are associated but separate dimensions or whether they share representational and processing resources. In the present study, we asked participants to judge whether a target vocal note was the same as (or different from) a preceding cue note. Importantly, target trials were presented as video clips where a singer sometimes gestured upward or downward while singing that target note, thus providing an alternative, concurrent source of spatial information. Our results show that pitch discrimination was significantly biased by the spatial movement in gesture, such that downward gestures made notes seem lower in pitch than they really were, and upward gestures made notes seem higher in pitch. These effects were eliminated by spatial memory load but preserved under verbal memory load conditions. Together, our findings suggest that pitch and space have a shared representation such that the mental representation of pitch is audiospatial in nature.     

Pliers,not fingers: Tool-action effect in a motor intention paradigm

Tool-use representations have been suggested to be supported by the representation of hand actions and/or by the representation of tool actions. A major issue is to know which one of these two representations is preferentially activated when people intend to use a tool. To address this issue, we developed a paradigm in which, in 20% of trials, participants had to press a button and actually use pliers to move an object in response to a predefined target symbol. Importantly, two masks hiding the symbols performed “opening” or “closing” actions before symbols appeared. In Experiment 1, participants used normal pliers: Hand’s opening actions induced pliers’ opening actions and vice versa for hands’ closing actions. Results indicated a compatibility effect between masks’ actions and pliers’ actions. Participants were faster to press the button in response to the target symbol when opening and closing actions of the masks were congruent with the corresponding actions of the hand. In Experiment 2 participants used inverse pliers: Hand’s opening actions involved pliers’ closing actions and vice versa. In this situation, results showed that the congruency of masks’ actions occurred with pliers’ actions and not hand’s actions. Altogether, these findings demonstrate that intention of use is preferentially based on the representation of tool actions, and have important implications for the domain of neuropsychology of tool use and the theories of goal-directed behavior.     

Playing on the typewriter, typing on the piano: manipulation knowledge of objects

Two experiments investigated sensory/motor-based functional knowledge of man-made objects: manipulation features associated with the actual usage of objects. In Experiment 1, a series of prime-target pairs was presented auditorily, and participants were asked to make a lexical decision on the target word. Participants made a significantly faster decision about the target word (e.g. ‘typewriter’) following a related prime that shared manipulation features with the target (e.g. ‘piano’) than an unrelated prime (e.g. ‘blanket’). In Experiment 2, participants' eye movements were monitored when they viewed a visual display on a computer screen while listening to a concurrent auditory input. Participants were instructed to simply identify the auditory input and touch the corresponding object on the computer display. Participants fixated an object picture (e.g. “typewriter”) related to a target word (e.g. ‘piano’) significantly more often than an unrelated object picture (e.g. “bucket”) as well as a visually matched control (e.g. “couch”). Results of the two experiments suggest that manipulation knowledge of words is retrieved without conscious effort and that manipulation knowledge constitutes a part of the lexical-semantic representation of objects.
