The influence of argument structure on judgements of argument strength,function, and adequacy

The present study explored the extent to which lay adults consider aspects of argument structure in judging the strength and function of informal arguments and in constructing arguments to meet specific adequacy goals. Across two experiments, college students were presented with base (one-premise) arguments, which were then expanded into convergent, coordinate, and subordinate arguments closely matched in terms of content, believability, and strength. Coordinate arguments were associated with the greatest gains in argument strength via their construction and the greatest loss in strength when one of their premises was falsified. To some degree, the argument types were also judged to perform different functions and to serve different goals. The construction of convergent arguments was associated with building independent lines of support while the construction of subordinate arguments was associated with providing justification for premises. Expansion into a coordinate argument was seen as the best way to improve an argument's persuasiveness. The construction of both coordinate and subordinate arguments was associated with building relevance, explicating assumptions, and completing the meaning of a base argument. Results are discussed in terms of argumentation theory and research.     

The influence of postural emotion cues on implicit trait judgements

Perceptions of others’ traits (e.g., trustworthiness or dominance) are influenced by the emotion displayed on their face. For instance, the same individual appears more trustworthy when they express happiness than when they express anger. This overextension of emotional expressions has been shown with facial expression but whether this phenomenon also occurs when viewing postural expressions was unknown. We sought to examine how expressive behaviour of the body would influence judgements of traits and how sensitivity to this cue develops. In the context of a storybook, adults (N?=?35) and children (5 to 8 years old; N?=?60) selected one of two partners to help face a challenge. The challenges required either a trustworthy or dominant partner. Participants chose between a partner with an emotional (happy/angry) face and neutral body or one with a neutral face and emotional body. As predicted, happy facial expressions were preferred over neutral ones when selecting a trustworthy partner and angry postural expressions were preferred over neutral ones when selecting a dominant partner. Children’s performance was not adult-like on most tasks. The results demonstrate that emotional postural expressions can also influence judgments of others’ traits, but that postural influence on trait judgments develops throughout childhood.

     

Causal judgements about two causal candidates: Accounting for occurrences,estimating strength,and the importance of interaction judgements

When two possible causes of an outcome are under consideration, contingency information concerns each possible combination of presence and absence of the two causes with occurrences and nonoccurrences of the outcome. White (2008) proposed that such judgements could be predicted by a weighted averaging model integrating these kinds of contingency information. The weights in the model are derived from the hypothesis that causal judgements seek to meet two main aims, accounting for occurrences of the outcome and estimating the strengths of the causes. Here it is shown that the model can explain many but not all relevant published findings. The remainder can be explained by reasoning about interactions between the two causes, by scenario-specific effects, and by variations in cell weight depending on quantity of available information. An experiment is reported that supports this argument. The review and experimental results support the case for a cognitive model of causal judgement in which different kinds of contingency information are utilised to satisfy particular aims of the judgement process.     

The influence of visual texture density gradients on relative distance judgements

A hypothesis derived from J. J. Gibson's psychophysical theory of space perception was tested. Subjects made monocular relative distance judgements by moving a marker to the apparent physical mid-point between two other fixed markers which were placed on a surface along the subjects' line of sight. Judgements were significantly influenced by the texture density gradients of stimulation derived from the surface over which they were made.     

The effects of confederate influence and confidence on the accuracy of crime judgements

Building on recent work which has investigated social influences on memory and remembering, the present experiment examined the effects of social pressure and confederate confidence on the accuracy and confidence of eyewitnesses. Sixty undergraduate participants watched a video of a staged mugging and then answered questions about the video out loud in the presence of either one or three confederates who had also watched the film with them. Unbeknownst to the participant, the confederate(s) always gave incorrect responses to four out of the eight questions. Participants and confederates were also asked to give confidence scores out loud for each of their answers. Again, unbeknownst to the participant, the confederate(s) always expressed either high or low confidence scores for the incorrect information, depending on condition. Participants gave fewer correct answers, and were less confident, in the presence of three, as opposed to one, confederates. Participants were also more confident, yet no more accurate, when the confederate(s) gave high, as opposed to low, confidence scores. Thus the presumed independence of evidence given by multiple witnesses cannot be safely assumed.     

The dissociable influence of social context on judgements of facial attractiveness and trustworthiness

The cheerleader effect occurs when the same face is rated to be more attractive when it is seen in a group compared to when seen alone. We investigated whether this phenomenon also occurs for trustworthiness judgements, and examined how these effects are influenced by the characteristics of the individual being evaluated and those of the group they are seen in. Across three experiments, we reliably replicated the cheerleader effect. Most faces became more attractive in a group. Yet, the size of the cheerleader effect that each face experienced was not related to its own attractiveness, nor to the attractiveness of the group or the group’s digitally averaged face. We discuss the implications of our findings for the hierarchical encoding and contrast mechanisms that have previously been used to explain the cheerleader effect. Surprisingly, judgements of facial trustworthiness did not experience a ‘cheerleader effect’. Instead, we found that untrustworthy faces became significantly more trustworthy in all groups, while there was no change for faces that were already trustworthy alone. Taken together, our results demonstrate that social context can have a dissociable influence on our first impressions, depending on the trait being evaluated.     

Emerging perspectives on the structure and function of attitude strength

For more than 20 years, scholars have used the term “attitude strength” to refer to the durability and impactfulness of attitudes, and a large literature attests to the important leverage that this concept offers for understanding and predicting behaviour. Despite its prominence, however, a number of fundamental questions remain regarding the structure and function of attitude strength. In this chapter we draw on a wide range of evidence to clarify the nature of attitude strength. Rather than conceiving of attitude strength as a meaningful psychological construct, we argue that it is better conceptualised as an umbrella term that refers in only the most general way to multiple, separable classes of attitude outcomes, instigated by different antecedents and produced by distinct psychological processes. Although strong attitudes share a set of general qualities—resistance to change, persistence over time, impact on thought and behaviour—there are many distinct routes by which attitudes come to possess these qualities, and many diverse ways in which these qualities manifest themselves. Our analysis shifts the focus away from the structural properties of attitude strength and towards a fuller appreciation of the distinct sources from which attitudes derive their strength. We argue in particular for the value of attending more closely to the social bases of attitude strength, and we illustrate the value of this approach by reviewing several lines of research.     

The sequential structure of odour mixture component intensity judgements

The use of linear multivariable time-series modelling, to disentangle sequential stimulus and response processes, is illustrated on a task involving judgements of the intensity of odour mixture components. A satisfactory fit of a model with no more than two lags is shown; the same model can represent diverse behaviour by internal parameter changes. The fundamental contrast between this dynamic approach and traditional static psychophysics is noted.     

The influence of spatial representation on valence judgements: An event-related potential study

The present study used event-related potentials (ERPs) to explore the nature of space-valence congruency effects. We presented participants with up or down arrows at the centre of the screen and then asked participants to identify whether the following target words had the emotional valence. The target words included positive emotional words (e.g., “happy” and “delight”), negative emotional words (e.g., “sad” and “depressive”) and neutral words (e.g., “history” and “country”). Behavioural data showed that the positive targets were identified faster when they are primed by up arrows than when primed by down arrows, whereas the negative targets were identified faster when they are primed by down arrows than when primed by up arrows. The ERP analysis showed larger P2 amplitudes were found in the congruent condition (i.e., the positive targets following up arrows or the negative targets following down arrows) than in the incongruent condition (i.e., the positive targets following down arrows or the negative targets following up arrows). Furthermore, larger N400 amplitudes were found in the incongruent condition compared with the congruent condition. Moreover, larger LPC amplitudes were found in the congruent condition compared with the incongruent condition. Therefore, in addition to replicating the space-valence congruency effects in a neutral/emotional judgement task, our study also extended previous studies by showing that spatial information modulates the processing of the emotional words at multiple stages.     

The relative influence of facial neoteny and waist-to-hip ratio on judgements of female attractiveness and fecundity

Numerous studies have demonstrated that waist-to-hip ratio (WHR) affects perceptions of female physical attractiveness and fecundity. This study tested the assumption that facial attractiveness explained more variance in overall ratings and fecundity than WHR, when the latter is manipulated within the normal range (0.67 - 0.85). One hundred and sixty-one participants (mean age = 21.5) rated the attractiveness, youthfulness, fertility, healthiness and likelihood of being pregnant for 27 photographs of three females in which facial attractiveness in terms of neoteny (three levels) and WHR (three levels) had been systematically digitally manipulated. Facial attractiveness exerted a significant influence on judgements of attractiveness, youthfulness, fertility and healthiness, whereas WHR only affected likelihood of being pregnant. Results are interpreted in terms of neotenous facial attractiveness providing potential mates with information concerning phenotypic and genetic quality.     

On the influence of affective states on intuitive coherence judgements

Recent research has shown that coherence judgements of semantically related word triads are facilitated by a subtle positive response triggered by their increased fluency of processing. Such positive affective response serves as a cue indicating semantic coherence. However, we argue that the fluency of processing is not the only source of affective response that can influence intuitive judgements. The present study investigated differential influences of mood and affective valence of solution words on intuitive coherence judgements. We show that affective cues resulting from processing fluency can be strengthened or weakened by inducing positive or negative affective response through the activation of solutions to semantically coherent triads. Also, mood is shown to impact the breadth of activated associations therefore affecting not only judgements of semantic coherence but also solvability of word triads. We discuss the implications of our findings for how people might form intuitive judgements of semantic coherence.

The role of trace strength in recency and frequency judgements by amnesic and control subjects

Amnesic and control subjects were required to judge the recency and frequency of presentation of complex pictures. The pictures were shown either once or three times 10 min or 24 h before testing. In both groups recency judgements were influenced by frequency of presentation, and frequency judgements by recency of presentation. Because the amnesic patients were unable to discriminate between the effects of repeated presentation and recent presentation, it was concluded that their judgements were determined solely by trace strength. Because controls showed some ability to make this discrimination, it was concluded that their judgements were determined jointly by trace strength and specific information about time and frequency of presentation.     

The knowledge argument,the open question argument,and the moral problem

Someone who knew everything about the world’s physical nature could, apparently, suffer from ignorance about various aspects of conscious experience. Someone who knew everything about the world’s physical and mental nature could, apparently, suffer from moral ignorance. Does it follow that there are ways the world is, over and above the way it is physically or psychophysically? This paper defends a negative answer, based on a distinction between knowing the fact that p and knowing that p. This distinction is made intelligible by reference to criterial connections between the possession of moral or phenomenal knowledge, and the satisfaction of cognitively neutral conditions of desire and experiential history. The existence of such connections in the moral case makes for an efficient dissolution of the so-called moral problem.     

Plausibility and argument structure in sentence comprehension

In two experiments, we investigated how reading time was affected by the plausibility of the prepositional phrase in subject-verb-noun-phrase-prepositional-phrase sentences, and the status of the prepositional phrase as argument versus adjunct of the verb. Highly plausible prepositional phrases were read faster than less plausible ones, and argument prepositional phrases were read faster than adjuncts. These effects appeared both in a self-paced reading experiment and in an experiment that measured eye movements during normal reading. The effects of plausibility were substantially larger and longer lasting than the effects of argument status, but both appeared very early in the reading of the prepositional phrase. The implications of these effects for models of parsing and sentence interpretation are discussed.
