Locating clicks in sentences: Left,center, and right

There are currently two theoretical interpretations of the pattern of errors that Ss make in attempting to locate the position of a click in a message. One is based upon lexical sequences in the message (the linguistic hypothesis), and the other is based upon attenti6nal priorities, memory factors, and response biases (the attentional hypothesis). This experiment was designed to differentiate between them. By orthogonally varying the temporal location of the major syntactic break and the position of the click, it was possible to control for effects of serial position and memory. In addition, a subliminal control group was run to evalute Ss’ response biases. Little evidence was found to support the linguistic hypothesis; considerable support was found for at least a qualitative version of the attentional hypothesis.     

Linguistic versus attentional influences on nonlinguistic categorization in 15-month-old infants

Why linguistic input facilitates nonlinguistic categorization is frequently explained in terms of children's attention to uniquely linguistic forms such as words. However, whether this facilitation is rooted in the children's attention to word forms very early in lexical learning has not been examined directly. A previous experiment (Roberts & Cuff, 1989) provided a set of conditions under which 15-month-olds did not successfully categorize in the absence of linguistic input. The two experiments reported here replicate Roberts and Cuff (1989) exactly, with the exception that either language (Experiment 1) or instrumental music (Experiment 2) was provided as accompanying input. Infants in both experiments successfully categorized and significantly increased attention during habituation. Although directly documenting the influence of language on categorization prior to the “vocabulary explosion,” this influence does not appear attributable to the presence of word forms. Instead, factors common to language and music (e.g., attention-getting properties or factors influencing attention) may facilitate nonlinguistic categorization at the beginnings of word learning.     

Stereotype susceptibility narrows the gender gap in imagined self-rotation performance

Three studies examined the impact of stereotype messages on men’s and women’s performance of a mental rotation task involving imagined self-rotations. Experiment 1 established baseline differences between men and women; women made 12% more errors than did men. Experiment 2 found that exposure to a positive stereotype message enhanced women’s performance in comparison with that of another group of women who received neutral information. In Experiment 3, men who were exposed to the same stereotype message emphasizing a female advantage made more errors than did male controls, and the magnitude of error was similar to that for women from Experiment 1. The results suggest that the gender gap in mental rotation performance is partially caused by experiential factors, particularly those induced by sociocultural stereotypes.     

Mood effects on attitude judgments: independent effects of mood before and after message elaboration.

This study investigated the independent effects of induced mood on the encoding of persuasive messages and on the assessment of attitude judgments. In Experiment 1, positive or negative mood was induced either before the encoding of a counterattitudinal message or before the assessment of attitude judgments. When mood was induced before message presentation, Ss in a bad mood were more persuaded by strong than by weak arguments, whereas Ss in a good mood were equally persuaded by strong and by weak arguments. When Ss encoded the message in a neutral mood, however, the advantage of strong over weak arguments was more pronounced when Ss were in a good rather than in a bad mood at the time of attitude assessment. In Experiment 2, Ss exposed to a counterattitudinal message composed of either strong or weak arguments formed either a global evaluation or a detailed representation of the message. Positive, negative, or neutral mood was then induced. Ss in a good mood were most likely and Ss in a negative mood least likely to base their reported attitudes on global evaluations.     

Promoting systematic processing in low-motivation settings: effect of incongruent information on processing and judgment

Ss received consensus information that was either congruent or incongruent with the valence of persuasive message content. In Experiment 1 Ss believed that their processing task was either important or unimportant whereas in Experiment 2 all Ss believed that their task was unimportant. In accord with the heuristic-systematic model's sufficiency principle, high-task-importance Ss exhibited a great deal of systematic processing regardless of congruency, whereas low-importance Ss processed systematically only when they received incongruent messages; in the congruent conditions heuristic processing dominated. Attitude data generally reflected these processing differences and confirmed the additivity and attenuation assumptions of the model. The utility of the sufficiency principle for understanding motivation for elaborative processing and the relevance of the findings to understanding the processing and judgmental effects of expectancy disconfirmation are discussed.     

Perceptions of source efficacy and persuasion: Multiple mechanisms for source effects on attitudes

When communicators are perceived as likely to bring proposed outcomes to fruition, they have source efficacy. Although perceptions of source efficacy are common in persuasion settings, this construct has received little direct research attention. The present research explored how source efficacy may impact persuasion in different ways at different levels of motivation to process messages. Across three experiments, participants encountered message arguments of varying quality from a source manipulated to be relatively efficacious or inefficacious. When motivation to process the message was low, source efficacy served as a peripheral cue (Experiment 1). When motivation was high, efficacy information learned before the message biased processing of ambiguous messages (Experiment 2), but source efficacy learned after the message affected the amount of confidence people had in their message‐related thoughts (Experiment 3). These effects of source efficacy were distinct from effects of perceived source expertise/credibility. Copyright © 2011 John Wiley & Sons, Ltd.     

On the orienting value of attitudes: attitude accessibility as a determinant of an object's attraction of visual attention.

Four experiments tested the hypothesis that objects toward which individuals hold attitudes that are highly accessible from memory (i.e., attitude-evoking objects) are more likely to attract attention when presented in a visual display than objects involving less accessible attitudes. In Experiments 1 and 2, Ss were more likely to notice and report such attitude-evoking objects. Experiment 3 yielded evidence of incidental attention; Ss noticed attitude-evoking objects even when the task made it beneficial to ignore the objects. Experiment 4 demonstrated that inclusion of attitude-evoking objects as distractor items interfered with Ss' performance of a visual search task. Apparently, attitude-evoking stimuli attract attention automatically. Thus, accessible attitudes provide the functional benefit of orienting an individual's visual attention toward objects with potential hedonic consequences.     

The use of visual context during the production of referring expressions

Most theories of reference assume that a referent's saliency in the linguistic context determines the choice of referring expression. However, it is less clear whether cognitive factors relating to the nonlinguistic context also have an effect. We investigated whether visual context influences the choice of a pronoun over a repeated noun phrase when speakers refer back to a referent in a preceding sentence. In Experiment 1, linguistic mention as well as visual presence of a competitor with the same gender as the referent resulted in fewer pronouns for the referent, suggesting that both linguistic and visual context determined the choice of referring expression. Experiment 2 showed that even when the competitor had a different gender from the referent, its visual presence reduced pronoun use, indicating that visual context plays a role even if the use of a pronoun is unambiguous. Thus, both linguistic and nonlinguistic information affect the choice of referring expression.     

Distinct Facial Characteristics Differentiate Communicative Intent of Infant‐Directed Speech

Adults and infants can differentiate communicative messages using the nonlinguistic acoustic properties of infant‐directed (ID) speech. Although the distinct prosodic properties of ID speech have been explored extensively, it is currently unknown whether the visual properties of the face during ID speech similarly convey communicative intent and thus represent an additional source of social information for infants during early interactions. To examine whether the dynamic facial movement associated with ID speech confers affective information independent of the acoustic signal, adults' differentiation of the visual properties of speakers' communicative messages was examined in two experiments in which the adults rated silent videos of approving and comforting ID and neutral adult‐directed speech. In Experiment 1, adults differentiated the facial speech groups on ratings of the intended recipient and the speaker's message. In Experiment 2, an original coding scale identified facial characteristics of the speakers. Discriminant correspondence analysis revealed two factors differentiating the facial speech groups on various characteristics. Implications for perception of ID facial movements in relation to speakers' communicative intent are discussed for both typically and atypically developing infants.

Systematic and heuristic processing of majority and minority-endorsed messages: the effects of varying outcome relevance and levels of orientation on attitude and message processing

Two experiments investigated the conditions under which majority and minority sources instigate systematic processing of their messages. Both experiments crossed source status (majority vs. minority) with message quality (strong vs. weak arguments). In each experiment, message elaboration was manipulated by varying either motivational (outcome relevance, Experiment 1) or cognitive (orientating tasks, Experiment 2) factors. The results showed that when either motivational or cognitive factors encouraged low message elaboration, there was heuristic acceptance of the majority position without detailed message processing. When the level of message elaboration was intermediate, there was message processing only for the minority source. Finally, when message elaboration was high, there was message processing for both source conditions. These results show that majority and minority influence is sensitive to motivational and cognitive factors that constrain or enhance message elaboration and that both sources can lead to systematic processing under specific circumstances.     

Mild Auditory-Visual Dissonance in Television News May Exceed Viewer Attentional Capacity

Two experiments examined how TV news viewers divide attention between the audio and video messages of news stories. The experiment tested the “belongingness” hypothesis which asserts that two distinct perceptual stimuli will be attended to as if they were a single stimulus when they appear to belong together. The experiments extended the belongingness hypothesis by manipulating semantic units (i.e., audio and video messages) rather than perceptual units. Auditory-visual redundancy was used to manipulate the belongingness variable. It was hypothesized that dissonant audio and video would be viewed as conveying two different messages, with the result that attentional capacity would be exceeded. Conversely, redundant stories would be viewed as conveying one message, with the results that attentional capacity would not be exceeded. Using secondary task methodology—reaction time tasks in Experiment 1 and memory preloads in Experiment 2—the belongingness hypothesis was supported.     

How do we communicate stereotypes? Linguistic bases and inferential consequences

The linguistic expectancy bias is defined as the tendency to describe expectancy-consistent information at a higher level of abstraction than expectancy-inconsistent information. The communicative consequences of this bias were examined in 3 experiments. Analyses of judgments that recipients made on the basis of linguistically biased information generated by transmitters indicated that behavior in expectancy-consistent messages was attributed more to dispositional and less to situational factors than behavior in expectancy-inconsistent messages. Moreover, this effect was mediated by the level of linguistic abstraction of the messages. These findings provide direct evidence for the hypothesis that recipients are sensitive to variations in linguistic abstraction in spontaneous language use because of stereotypes. Results are discussed with respect to the interpersonal aspects of stereotyping.     

Does affect induce self-focused attention?

Despite growing evidence that depression is linked with self-focused attention, little is known about how depressed individuals become self-focused or, more generally, about what arouses self-focus in everyday life. Two experiments examined the hypothesis that affect itself induces self-focused attention. In Experiment 1, moods were manipulated with an imagination mood-induction procedure. Sad-induction Ss became higher in self-focus than did neutral-induction Ss. Experiment 2 replicated this effect for sad moods by means of a musical mood-induction procedure and different measures of self-focus. However, Experiment 2 failed to support the hypothesis that happy moods induce self-focus. The results have implications for mood-induction research, self-focused attention, and recent models of depression.     

Message Planning,Communication Failure,and Cognitive Load Further Explorations of the Hierarchy Principle

The hierarchy principle predicts and research has demonstrated that in response to communication failure, individuals make less cognitively demanding, low-level changes to message plans, such as the vocal intensity at which they are delivered, rather than more demanding alterations to message content and structure. Three experiments examined the effects of different message preparations on cognitive loads associated with high-level message plan alterations. In Experiment 1, individuals who prepared only one highly iconic message before experiencing communication failure demonstrated greater cognitive load when requested to deliver an alternative message than did individuals who prepared three highly iconic alternative messages. No cognitive load differences were found between those who prepared one or three low-iconicity messages. In Experiment 2, individuals who prepared one or six highly iconic message plans demonstrated greater cognitive load after communication failure than those who prepared three alternatives. This U-curve relationship was replicated in Experiment 3.     

Cognitive Processing and the Functional Matching Effect in Persuasion: The Mediating Role of Subjective Perceptions of Message Quality

In two experiments, we examined the hypothesis that subjective perceptions of message quality mediate the functional matching effect in persuasion. In Experiment 1, participants whose attitudes and behaviors serve primarily a value-expressive function (i.e., low self-monitors) or a social-adjustive function (i.e., high self-monitors) were exposed to persuasive messages that contained value-expressive, social-adjustive, or both types of arguments in favor of voting. Functionally-relevant messages (i.e., the social-adjustive message for high self-monitors and the value-expressive message for low self-monitors) produced enhanced perceptions of message quality and persuasiveness, more positive attitudes, and more message-related behavior than functionally nonrelevant messages. Functionally mixed messages were generally more effective than messages containing only functionally nonrelevant arguments, but less effective than messages containing only functionally relevant arguments. Path analyses indicated that the influence of functional relevance on attitudes and behavior was significantly mediated by subjective perceptions of the quality of the message. In Experiment 2, we exposed participants to a functionally relevant or nonrelevant voting appeal five days before a presidential election. Results replicated those of Experiment 1; functionally relevant messages produced more favorable attitudes, and this effect was mediated by enhanced perceptions of message quality. Finally, postmessage attitudes exerted a significant influence on whether participants voted in the election, and this effect was mediated by voting intentions. Discussion focuses on the subjective nature of message evaluation and on the cognitive processes underlying the functional matching effect in persuasion.     

Hemispheric prevalence in acoustical attention

Two experiments were conducted in which monaural clicks were presented to the right or left ear preceded by biaural verbal (Experiment 1) and musical (Experiment 2) warnings. After the “neutral” warnings, the clicks could be presented to the right or left ear equally often (50%); after the warnings which directed the attention to the left or right ear, the clicks could be presented to either the “expected” (67%) or to the “unexpected” (33%) ear. In Experiment 1 there was a cost effect for the “unexpected” ear and reaction times were significantly faster when the clicks were presented to the right ear. In Experiment 2, the musical warnings brought about a cost effect while no significant ear advantage was observed.     

Undoing the Effects of Seizing and Freezing: Decreasing Defensive Processing of Personally Relevant Messages

Health messages are directed at those who are at risk of incurring adverse consequences. However, previous experiments have found that people process personally relevant health messages in a biased, defensive manner. We examine the role of elaboration as a mechanism to encourage less biased processing of personally relevant health appeals. Results demonstrate that high-relevance consumers freeze on the threatening information, leading to lower change appraisal (perceived severity, self-efficacy, and response efficacy) and decreased message persuasion. For these individuals, renewed elaboration on the consequences of caffeine (Experiment 1) and olestra (Experiment 2) consumption reduces defensive processing. This elaboration "unfreezes" message processing, leading to greater change appraisal and increased persuasion. These experiments provide guidelines for practitioners to design more effective messages.     

The stimulus suffix effect as a memory coding phenomenon

Two short-term memory experiments examined the nature of the stimulus suffix effect on auditory linguistic and nonlinguistic stimulus lists. In Experiment 1, where subjects recalled eight-item digit lists, it was found that a silently articulated digit suffix had the same effect on recall for the last list item as a spoken digit suffix. In Experiment 2, subjects recalled lists of sounds made by inanimate objects either by listing the names of the objects or by ordering a set of drawings of the objects. Auditory suffixes, either another object sound or the spoken name of an object, produced a suffix effect under both recall conditions, but a visually presented picture also produced a suffix effect when subjects recalled using pictures. The results were most adequately explained by a levels-of-processing memory coding hypothesis.     

The influence of evidence type and product involvement on message‐framing effects in advertising

• Extrapolating from prior research that describes the persuasive effects of gain‐ versus loss‐framed messages via the heuristic‐systematic model (HSM), the current study incorporated two advertising‐related factors – evidence type (informational vs. exemplar) and product involvement – and examined their influence on message‐framing effects in advertisements for commonplace consumer products. A significant interaction in Experiment 1 indicated that loss‐framed messages were persuasive in a higher‐involvement context only when coupled with informational evidence, which enhanced systematic processing among participants and thereby elicited the framing effect. No interaction effects occurred in the lower‐involvement context of Experiment 2, in which the hypothesized thought‐processing patterns did not evince. Consistent with recent theoretical advancements, these results indicate that message‐framing effects can be attenuated when both systematic and heuristic processing occur simultaneously. Practical implications are discussed.

Assimilation and contrast in persuasion: the effects of source credibility in multiple message situations

The present research explores a contextual perspective on persuasion in multiple message situations. It is proposed that when people receive persuasive messages, the effects of those messages are influenced by other messages to which people recently have been exposed. In two experiments, participants received a target persuasive message from a moderately credible source. Immediately before this message, participants received another message, on a different topic, from a source with high or low credibility. In Experiment 1, participants' attitudes toward the target issue were more favorable after they had first been exposed to a different message from a low rather than high credibility source (contrast). In Experiment 2, this effect only emerged when a priming manipulation gave participants a dissimilarity mindset. When participants were primed with a similarity mindset, their attitudes toward the target issue were more favorable following a different message from a high rather than low credibility source (assimilation).
