The negative priming effect: Inhibitory priming by ignored objects

A priming paradigm was employed to investigate the processing of an ignored object during selection of an attended object. Two issues were investigated: the level of internal representation achieved for the ignored object, and the subsequent fate of this representation. In Experiment 1 a prime display containing two superimposed objects was briefly presented. One second later a probe display was presented containing an object to be named. If the ignored object in the prime display was the same as the subsequent probe, naming latencies were impaired. This effect is termed negative priming. It suggests that internal representations of the ignored object may become associated with inhibition during selection. Thus, selection of a subsequent probe object requiring these inhibited representations is delayed. Experiment 2 replicated the negative priming effect with a shorter inter-stimulus interval. Experiment 3 examined the priming effects of both the ignored and the selected objects. The effect of both identity repetition and a categorical relationship between prime and probe stimuli were investigated. The data showed that for a stimulus selected from the prime display, naming of the same object in the probe display was facilitated. When the same stimulus was ignored in the prime display, however, naming of it in the probe display was again impaired (negative priming). That negative priming was also demonstrated with categorically related objects suggests that ignored objects achieve categorical levels of representation, and that the inhibition may be at this level.     

The affective priming effect: Automatic activation of evaluative information in memory

Abstract

Fazio, Sanbonmatsu, Powell, and Kardes (1986) argued that affect may be activated automatically from memory on the mere observation of an affect-loaded stimulus. Using a variant of the standard sequential priming paradigm, it was demonstrated that the time needed to evaluate target words as positive or negative decreased if they were preceded by a similarly valenced prime word, but increased when preceded by a prime of opposite valence. Several aspects of their procedure, however, do not warrant their conclusion concerning the unconditionality of the effect. The present research investigated the generality of this affective priming effect. In Experiment 1, it was tested whether the effect can be generalised to more complex visual material. Stimulus pairs consisted of colour slides. Subjects had to evaluate the targets as quickly as possible. In Experiment 2, the standard word-word procedure was used, but target words had to be pronounced. In both experiments, significant affective priming effects were observed, supporting Bargh, Chaiken, Govender, and Pratto's (1992) assertion that the automatic activation effect is a pervasive and relative unconditional phenomenon. Implications for theories of affect and emotion are discussed.     

On the futility of psychiatric diagnostic manuals (DSMs) and the return of personal agency

This article critiques the most recent version of the American Psychiatric Association's (1994) Diagnostic and Statistical Manual (DSM-IV). After pointing to the procedures employed in constructing the Manual, I note that unreliability of diagnosis is still a major problem and, more important, little attention has been paid to validity. Based on the mechanistic Kraepelinian model, the Manual contributes to the increasing medicalization of distress and directs clinicians to search for causes of unwanted behavior in biochemical anomalies. The person as agent is not part of the DSM diagnostic program. As an alternative to the DSM-IV, I propose a contextualist approach to understanding unwanted conduct. The person is treated as an agent who employs strategic actions to maintain a self-narrative. Strategic actions that fail to influence relevant others to supply warrants of social validation become the targets of clinical interventions.     

On the nature of the proportion effect in semantic priming

The purpose of the present study was to investigate the nature of the proportion effect in semantic priming. The experiment employed a lexical decision task under conditions of low, medium, and high proportion of related pairs with an SOA of 550 msec. The results indicated that the higher proportions of related trials had a facilitatory effect on targets preceded by related primes as compared with a neutral priming condition. In comparing the unrelated trials with the neutral trials there is an increase in the inhibitory effect associated with unrelated pairs as the proportion of related pairs increases. The proportion of related items did not affect the nonword responses. In addition, practice was not found to have a significant effect in any of the conditions. It was concluded that the proportion effect could best be explained by a post-lexical coherence checking mechanism within the constraints of the present experiment.     

Decision-making by experienced rugby referees: use of perceptual information and episodic memory

The expertise paradigm was used in two studies to examine decision-making by rugby referees. Videoclips were used to assess infraction detection and knowledge base, or sources of information used. In Study 1, referees of high and low experience were compared, and in Study 2 referees and players were compared. Analysis by signal detection used a framework to classify types of information. Study 1 yielded no differences in detection of infractions as a function of experience, however, referees of high experience used significantly more sources of information than the group with low experience across all categories of information. In Study 2, there were no significant differences between referees and players, with the exception that referees displayed greater use of episodic memory information in decision-making.     

On the replicability of the affective priming effect in the pronunciation task

Bargh, Chaiken, Raymond, and Hymes (1996) and Hermans, De Houwer, and Eelen (1994) showed that a valenced target word is pronounced faster after the presentation of an affectively related prime word than after the presentation of an affectively unrelated prime word. This finding is important because it provides crucial evidence for the hypotheses that stimulus evaluation (a) is goal-independent and (b) facilitates the encoding of stimuli that have the same valence. However, recent studies indicate that the affective priming effect is not a reliable finding in the standard pronunciation task. We report the results of a nearly exact replication of Bargh et al.'s (1996) Experiment 2. In line with previous replication studies, we failed to detect the affective priming effect.     

Semantic priming of person recognition: Categorial priming may be a weaker form of the associative priming effect

An interactive activation and competition account (Burton, Bruce, & Johnston, 1990) of the semantic priming effect in person recognition studies relies on the fact that primes and targets (people) have semantic information in common. However, recent investigations into the type of relationship needed to mediate the semantic priming effect have suggested that the prime and target must be close associates (e.g., Barry, Johnston, & Scanlan, 1998; Young, Flude, Hellawell, & Ellis, 1994). A review of these and similar papers suggests the possibility of a small but non-reliable effect based purely on categorial relationships. Experiment 1 provided evidence that when participants were asked to make a name familiarity decision it was possible to boost this small categorial effect when multiple (four) primes were presented prior to the target name. Results from Experiment 2 indicated that the categorial effect was not due to the particular presentation times of the primes. This boosted categorial effect was shown to cross domains (names to faces) in Experiment 3 and persist in Experiment 4 when the task involved naming the target face. The similarity of the pattern of results produced by the associative priming effect and this boosted categorial effect suggests that the two may be due to the same underlying mechanism in semantic memory.     

On the locus of priming and inverse priming effects

Visual stimuli that are made invisible by a following mask can affect overt motor responses and nonmotor processing. Previous studies have compared the effects of primes that were perceptually similar to the subsequent stimulus with those of primes that were perceptually similar to an alternative stimulus. The present study examined the effect of congruent primes that are perceptually dissimilar to the target (or the cue) but are nonetheless associated with the same response (or the same task) as the later stimulus. Positive and inverse priming effects (negative compatibility effects) were studied in a target priming paradigm (Experiments 1 and 2) and in a cue priming paradigm (Experiments 3 and 4). The results showed stronger priming effects with similar primes than with dissimilar congruent primes. However, the effects of perceptually dissimilar congruent primes differed from those of dissimilar incongruent primes. These findings suggest that a substantial part of both positive target and cue priming effects is produced at levels of processing that are not affected by perceptual similarity. The version of inverse priming effects examined in this study, however, seems to arise from perceptual processing that is affected by the similarity between a prime and the stimulus that follows the mask.     

Masked priming effect reflects evidence accumulated by the prime

In the same–different match task, masked priming is observed with the same responses but not different responses. Norris and Kinoshita's (2008) Bayesian reader account of masked priming explains this pattern based on the same principle as that explaining the absence of priming for nonwords in the lexical decision task. The pattern of priming follows from the way the model makes optimal decisions in the two tasks; priming does not depend on first activating the prime and then the target. An alternative explanation is in terms of a bias towards responding “same” that exactly counters the facilitatory effect of lexical access. The present study tested these two views by varying both the degree to which the prime predicts the response and the visibility of the prime. Unmasked primes produced effects expected from the view that priming is influenced by the degree to which the prime predicts the response. In contrast, with masked primes, the size of priming for the same response was completely unaffected by predictability. These results rule out response bias as an explanation of the absence of masked priming for different responses and, in turn, indicate that masked priming is not a consequence of automatic lexical access of the prime.     

The impact of affective information on the professional judgments of more experienced and less experienced auditors

This study examines whether the presence of realistic, yet irrelevant, affective information differentially influences the professional judgments of more experienced and less experienced auditors. In this study, auditors with different experience levels were either provided or not provided with information designed to elicit a negative interpersonal emotional reaction towards a manufacturing client when making an inventory obsolescence risk judgment. The results indicate that the inventory obsolescence risk assessments of less experienced auditors were significantly higher when they were provided with negative affective information on a client than when no such information was provided. No such differences were found for the more experienced auditors. This study suggests that professional experience is one factor that influences individuals' assessments of the informational value of affective reactions. This has implications for developing effective training programs to increase professionals' awareness of the influence that emotional reactions can have on their judgment.

Effects of fatigue on ability to process visual information by experienced orienteers

6 experienced orienteers were subject to a VO2max treadmill test, two days prior to undertaking two tests of visual perception. One test was conducted while the subjects were in a rested state while the other was conducted while they were under a state of fatigue. Fatigue was defined as a state in which the subjects were working at or above their anaerobic threshold which had been determined previously from their VO2max test. The tests in both the fatigue and rest condition were of a similar nature, that is, the subjects were presented slides of orienteering checkpoints at regular intervals followed by a slide showing a set of questions which the subjects had to answer verbally. Two sets of slides were employed and these were approximately counterbalanced between both subjects and conditions. Points were awarded for the correct answers and the two conditions were then compared. The Wilcoxon test for two correlated samples was used and showed a significant difference between the fatigue and rest scores at p less than 0.05. The data suggest that under the influence of fatigue, an orienteer's ability to perceive visual information is greatly impaired.     

The effect of personal attitudes on information processing biases in religious individuals

Selective exposure, the confirmation bias of preferring attitude-consistent over attitude-inconsistent information, is empirically a well-established phenomenon of human behaviour. However, most of the research on selective exposure has been conducted either on what material participants select or what they attend to once the material is presented. We extended a selective exposure paradigm by measuring biases at both the selection and the reading stages of information processing. After Christian participants (n?=?41) were asked about their views on tithing (a religious practice of giving charity), selective exposure biases were not systematic but were moderated by participants’ views on tithing. That is, those who were in favour of tithing showed a preference for anti-tithing material (i.e. attitude-inconsistent material), whereas those who were not in favour of tithing also showed a preference for anti-tithing material (i.e. attitude-consistent material). Our study indicates that resistance to persuasion might in some cases depend on attitude direction.     

Predicting adolescent eating and activity behaviors: the role of social norms and personal agency.

Guided by the theory of planned behavior, this 2-week longitudinal study examined health behaviors in a sample of 279 adolescents. Social norms and perceived behavioral control (PBC) were tested as predictors of self-reported intentions and behaviors in 2 domains, eating and physical activity. Differentiating, as opposed to aggregating, parent and peer norms provided unique information. For PBC, the authors distinguished global causality beliefs from self-related agency beliefs and intraself (effort, ability) from extraself (parents, teachers) means. Intraself agency beliefs strongly predicted healthy intentions, whereas intraself causality beliefs had a negative influence. Patterns differed somewhat across behaviors and gender. Results highlight theoretical issues and provide potential targets for research on health promotion programs for youth.     

The nonconscious road to perceptions of performance: Achievement priming augments outcome expectancies and experienced self-agency

Three experiments explored the effects of priming the achievement concept on the expectation of performance outcomes and experiences of self-agency over outcomes in a task in which performance outcomes were dependent on chance. Experiment 1 and 2 showed that achievement priming produced expectations of higher (more successful) outcomes prior to working on the task, regardless of whether priming was subliminal (nonconscious) or supraliminal (conscious) and that this effect could not be attributed to subjective motivation to perform well. Experiment 3 revealed that subliminal achievement priming decreased participants’ experienced self-agency when outcome feedback was low, but increased self-agency when it was high. Together, these results suggest that activating achievement concepts outside of awareness spontaneously triggers expectations of higher task outcomes, which increases or decreases self-agency depending on whether there is a match or mismatch with observed outcomes. Implications for the literature on achievement-priming effects on behavior are discussed.     

Close relationships and the working self-concept: implicit and explicit effects of priming attachment on agency and communion

Two studies investigated how contextually activating attachment relationships influences the working self-concept in terms of agency and communion. In Study 1, 245 participants were primed with a secure, avoidant, or anxious-ambivalent relationship and the implicit accessibility of agency and communion was assessed using word fragments. Activating a secure relationship increased the accessibility of communion, whereas activating an anxious-ambivalent relationship increased the accessibility of agency. In Study 2, 123 participants were primed with a secure, preoccupied, avoidant-dismissive, or avoidant-fearful relationship and explicit self-perceptions of agency and communion traits were assessed using the Extended Personality Attributes Questionnaire (EPAQ). Gender interacted with the attachment prime, such that men primed with a secure relationship reported higher communion than did men primed with an avoidant (dismissive or fearful) relationship, whereas women primed with an anxious (preoccupied or fearful) relationship reported higher agency than did women primed with a secure relationship.     

Morphological priming effect: the role of surface frequency.

Two cross-modal experiments were conducted to investigate the format of lexical representation of suffixed derived words and their stems. The results show that only low frequency suffixed words (as opposed to high frequency suffixed words) yield a full priming effect of their stems. By contrast, a stem (e.g., travail) does not fully prime words belonging to the same morphological family (e.g., travailleur), although it primes high frequency suffixed words more than it does low frequency words. To account for these findings we propose a model in which the stem and high frequency affixed words are represented both as full forms and as decomposed morphemes while low frequency affixed words are represented only in a decomposed form.
