Get the picture? The effects of iconicity on toddlers' reenactment from picture books

What do toddlers learn from everyday picture-book reading interactions? To date, there has been scant research exploring this question. In this study, the authors adapted a standard imitation procedure to examine 18- to 30-month-olds' ability to learn how to reenact a novel action sequence from a picture book. The results provide evidence that toddlers can imitate specific target actions on novel real-world objects on the basis of a picture-book interaction. Children's imitative performance after the reading interaction varied both as a function of age and the level of iconicity of the pictures in the book. These findings are discussed in terms of children's emerging symbolic capacity and the flexibility of the cognitive representation.     

Does aversive behavior during toddlerhood matter? The effects of difficult temperament on maternal perceptions and behavior

Seventy‐three mothers and their toddlers were observed when the children were 18 and 24 months of age in a series of laboratory procedures designed to assess relations among frustration distress, aggression/venting, and defiance, as indicators of aversive behavior, and their relations to maternal interactive style concurrently and over time. A second goal was to identify the predictors of aversive behavior at 24 months of age. Child aversive behavior as a predictor of increases in maternal negativity over time was also examined. Results indicated that distress, venting, and defiance were related to one another at 18 months of age. For boys, venting at 24 months of age, but not distress or defiance, was associated with greater maternal report of stress and higher incidence of behavior problems at 24 months of age. Venting behavior at 24 months of age was predicted by the interaction of early aversive behavior and low maternal positive guiding behavior. Increases in maternal negative behavior over the six‐month period were predicted by the interaction of earlier negative maternal behavior and child sex, with negative mothers of boys displaying greater increases in negative behavior at the later age. These findings are discussed in terms of the significance of early aversive behavior, in the context of mother–child interaction, for later problematic behavior. ©2002 Michigan Association for Infant Mental Health.     

Is a picture worth a thousand words? Evidence from concept definitions by patients with semantic dementia

Nine patients with semantic dementia (the temporal lobe variant of frontotemporal dementia) were asked to define concrete concepts either from presentation of a picture of the object or from its spoken name. As expected, the patients with the most severe semantic impairment produced the least detailed definitions, and the quality of the definitions overall was significantly related to concept familiarity. Further analyses of the definitions were designed to assess two key theoretical aspects of semantic organization. (i) Do objects and their corresponding names activate conceptual information in two neuroanatomically separable (modality-specific) semantic systems? If so, then-apart from any expected commonality in performance attributable to factors such as concept familiarity-one would not predict striking item-specific similarities in a patient's picture- and word-elicited definitions. (ii) Do sensory/perceptual features and more associative/functional attributes of conceptual knowledge form two neuroanatomically separable subsystems? If so, then one would predict significant dissociations in the prominence of these two types of information in the patients' definitions. The results lead us to favor a model of the semantic system that is divided by attribute type but not by modality.     

A picture is worth a thousand words: a comparison of pupils’ images of intelligence in Finnish and Russian Karelia

The study set out to examine Finnish and Russian children’s images of intelligence as contextualized in the systems of the school and gender. Finnish and Russian pupils, aged 11–12 years, were asked to draw pictures of an intelligent and an ordinary pupil and a good and an ordinary pupil. A distinctive feature shared by the children in both countries was that intelligent pupils were depicted as positively orientated to knowledge and studies and as similar to good pupils. The Russian children’s pictures emphasized academic performance, suggesting that the contribution of the school to children’s representations was greater in Russia than in Finland. In regard to gender appearance, the intelligent pupil was usually pictured in gender-neutral or childish features, suggesting that being defined as intellectually competent entailed deviating from the heterosexual ideal. In the discussion, the ambivalence associated with social definitions of intelligence is addressed.     

Attibution of attitudes to speakers and listeners under assigned-behavior conditions: Does behavior engulf the field?

A conceptual replication of the assigned-behavior conditions of previous research in attitude attribution was conducted. Participants made attitude attributions about themselves and also about others who had either given, listened to, or not been exposed to either a proattitudinal or counterattitudinal essay. The position adopted in the essay significantly affected the attitudes attributed to those assigned to deliver the essay. Essay position had an equally strong effect upon attitudes attributed to those who merely listened to the essay, however. Thus, the fact that the actor had delivered a particular assigned essay apparently did not in itself convey information to the observers about the actor's attitudes. Experimental results suggested that essay direction affects attitudes attitudes attributed to others in an assigned-behavior setting because observers use their own attitudes to infer the attitudes of others. Since observers' own attitudes change after exposure to different essays, they attribute different attitudes to others.     

What's in a picture? The impact of face-ism on trait attribution

Previous research indicated a ‘face-ism’ bias in media depictions of men and women: me media tend to represent men with their faces, whereas women's depictions include larger parts of their bodies, rendering their faces less prominent. To explore the impact of facial prominence on impression formation, male and female subjects received either full-body or portrait-style photographs, made from the same negatives, of male and female stimulus persons of different likeability. Male and female subjects evaluated all stimulus persons as more competent (intelligent, assertive, ambitious, etc.) if presented with a high (portrait) rather than a low (full-body photograph) degree of facial prominence. This main effect of facial prominence was not qualified by interaction effects with any of the other variables. PIUS, the media's face-ism bias is likely to contribute to a perception of men as more competent than women. In addition, female but not male subjects also evaluated stimulus persons as more expressive and likeable under conditions of high facial prominence, reflecting a global positive effect of facial prominence.     

The ecology of self-monitoring effects on memory of verbal productions: Does speaking to someone make a difference?

Experiments involving verbal self-monitoring show that memory for spoken words varies with types of sensory feedback: memory is better when words are spoken aloud than when they are lip-synched or covertly produced. Such effects can be explained by the Central Monitoring Theory (CMT) via a process that matches a forward model reflecting expected sensory effects of practiced forms and sensory information during speech. But CMT oversees factors of shared attention as achieved by speaker–listener gaze, and implies that sensory feedback may not affect the learning of unpracticed forms (non-words). These aspects of CMT were examined in two experiments of self-monitoring focusing on oro-sensory feedback. In Experiment 1 we show that varying feedback creates differential effects on memory for spoken words and that speaker–listener gaze alters these effects. Using non-words, Experiment 2 shows the absence of differential feedback effects. The results confirm CMT but suggest the need to refine the theory in terms of processes that mediate attention.     

The combined effects of risk and time on choice: Does uncertainty eliminate the immediacy effect? Does delay eliminate the certainty effect?

Researchers have noted parallels between decisions under uncertainty and over time. Three experiments evaluated the theory that uncertainty and time affect choice via a common underlying dimension, such that delaying an outcome is equivalent to making it uncertain. To test this account we asked whether adding uncertainty to outcomes would eliminate the immediacy effect bias. We also asked whether adding time delay to outcomes would eliminate the certainty effect bias. The answer to both questions was yes, provided the prospects were presented singly rather than jointly. In single evaluation uncertainly eliminated the immediacy effect and delay eliminated one form of the certainty effect, while in joint evaluation, these effects did not occur. These findings suggest that at least in some contexts decision makers may equate risk and delay. Other explanations are possible, however, demonstrating that the interaction between risk and delay is complex and not easily understood.     

The combined effects of plane disorientation and foreshortening on picture naming: one manipulation or two?

Objects disoriented in plane away from the upright and objects rotated in depth producing foreshortening are harder to identify than canonical views. In Experiments 1 and 2, participants named pictures of familiar objects. There was no interaction between plane and depth rotation effects on initial presentation or after practice. Experiment 3 was a dual-task psychological refractory period study. Participants classified a high-low tone with a speeded keypress and then named a canonical, plane-rotated, or foreshortened view of an object. Naming was slower when the picture was presented 50 ms after the tone compared with 800 ms after the tone. Plane rotation effects were reduced (but not eliminated) at the short tone-picture stimulus onset asynchrony, but foreshortening effects were not reduced. The results implicate an early, prebottleneck locus for some processes compensating for plane rotation and a subsequent bottleneck or postbottleneck locus for compensation for foreshortening.     

On the process of recognizing inverted words: Does it rely only on orientation-invariant cues?

Following a demonstration by Parks (1983) of failure to notice the reflection of a letter of an inverted word, two experiments were conducted to test a hypothesis about the process of recognizing inverted words that is termed here invariant cues only (ICO)-a letter-by-letter identification process based only on orientation-invariant letter features. In Experiment 1, subjects were presented with whole strings-words and nonwords, either upright or inverted-in which either all the letters were normal or one of the letters was reflected, and they were asked to make lexical decisions. In Experiment 2, subjects made a reflection judgment about an upright or inverted letter within a string immediately after they had been presented with the other, nonreflected string letters, again either upright or inverted. The results do not support the ICO hypothesis: Lexical decisions were greatly affected by the reflection of a letter in upright and inverted stimuli alike. Reflection judgments were considerably facilitated by word context in the upright and the inverted modes alike. The results are accommodated better by the notion that recognition of disoriented words requires some correction used to restore orientation-sensitive features.     

Use of positive interventions: Does neuroticism moderate the sustainability of their effects on happiness?

Previous research indicates that performing positive activities boosts happiness. The present studies examined whether neuroticism would moderate the sustainability of the effects of positive activities on happiness. Study 1 showed that the effects of counting blessings/kindness daily for seven days lasted a week after participants stopped performing the activity, but only for low-neuroticism individuals (who reported increased happiness) and not high-neuroticism individuals. However, a week post-intervention, gratitude-/kindness-listing participants were more likely to choose an amusing rather than a sad film, regardless of neuroticism differences. This suggests that behavioral choice is more sensitive to positive intervention effects than self-reported happiness. In Study 2, high-neuroticism individuals who occasionally visualized and wrote about their best possible selves over three weeks were happier than their counterparts in the control condition. The present research illustrates that although neuroticism moderates the sustainability of positive intervention effects, encouraging continuance of positive activities may produce more lasting effects.     

Are the fruits of research available to all? The effects of sex and academic rank on reprint-sending behavior

There is considerable evidence in the psychological literature that perceived status often has a major effect on behavior. The primary purpose of the present study was to examine the effects of two status variables in an academic setting by monitoring reprint-sending behavior. Reprints were requested from 1,200 authors of psychological articles by men and women of varying academic rank. Neither sex nor academic rank of requester had any significant effect on the total number of responses returned. However, male requesters received responses significantly faster than did female requesters. In addition, subsequent analyses indicated that reprint requests were more likely to be honored by male authors than by female authors.     

Does the advantage of the upper part of words occur at the lexical level?

Several recent studies have shown that the upper part of words is more important than the lower part in visual word recognition. Here, we examine whether or not this advantage arises at the lexical or at the letter (letter feature) level. To examine this issue, we conducted two lexical decision experiments in which words/pseudowords were preceded by a very brief (50-ms) presentation of their upper or lower parts (e.g., ). If the advantage for the upper part of words arises at the letter (letter feature) level, the effect should occur for both words and pseudowords. Results revealed an advantage for the upper part of words, but not for pseudowords. This suggests that the advantage for the upper part of words occurs at the lexical level, rather than at the letter (or letter feature) level.     

A mouse with a roof? effects of phonological neighbors on processing of words in sentences in a non-native language

The architecture of the language processing system for speakers of more than one language remains an intriguing topic of research. A common finding is that speakers of multiple languages are slower at responding to language stimuli in their non-native language (L2) than monolingual speakers. This may simply reflect participants' unfamiliarity with words in the L2, however it may also be the reflection of interference from competing lexical alternatives both across and within the participants' multiple languages. In the current studies (one behavioral, one electrophysiological) we investigate how interference from phonologically similar words within the L2 alone may account for problems in auditory language comprehension in non-native speakers. To this end a cross modal lexical priming (CMLP) paradigm was implemented, which allowed us to look for effects of spoken word primes embedded in sentences on the recognition of target stimuli. Specifically, we investigated whether a word such as mouse, which has a close phonological neighbor, house, would show a modulating effect on recognition of a word semantically related to house but not to mouse (i.e., roof). We hypothesized that L2 speakers, less efficient at categorizing phonemes in their L2 would show a difference in the processing of roof preceded by mouse as compared to roof preceded by another unrelated word, such as lamp, due to a residual co-activation of the phonological neighbor mouse. Furthermore, L1 speakers, highly proficient at recognizing phonemes in their native tongue, should show no such effect. The results of both studies clearly support our hypothesis, indicating that phonological neighbors in the L2 may greatly interfere with L2 word recognition.     

Belief-desire reasoning in the explanation of behavior: do actions speak louder than words?

The mechanisms underwriting our commonsense psychology, or 'theory of mind', have been extensively investigated via reasoning tasks that require participants to predict the action of agents based on information about beliefs and desires. However, relatively few studies have investigated the processes contributing to a central component of 'theory of mind' - our ability to explain the action of agents in terms of underlying beliefs and desires. In two studies, we demonstrate a novel phenomenon in adult belief-desire reasoning, capturing the folk notion that 'actions speak louder than words'. When story characters were described as searching in the wrong place for a target object, adult subjects often endorsed mental state explanations referencing a distracter object, but only when that object was approached. We discuss how this phenomenon, alongside other reasoning "errors" (e.g., hindsight bias; the curse of knowledge) can be used to illuminate the architecture of domain specific belief-desire reasoning processes.     

Does the Traditional Treatment of Enthymemes Rest on a Mistake?

In many actual arguments, the conclusion seems intuitively to follow from the premisses, even though we cannot show that it follows logically. The traditional approach to evaluating such arguments is to suppose that they have an unstated premiss whose explicit addition will produce an argument where the conclusion does follow logically. But there are good reasons for doubting that people so frequently leave the premisses of their arguments unstated. The inclination to suppose that they do stems from the belief that the only way in which an argument's conclusion can follow definitely from its premisses is to follow logically. I argue that this belief is mistaken. I propose a revision of the current generic conception of logical consequence, and its variant specifications, to avoid the paradoxes of strict implication. The revised conception can then be naturally extended to include also what we might call 'enthymematic consequence'. This concept is a kind of consequence, whose properties merit investigation.     

The Impact of Faking on Employment Tests: Does Forced Choice Offer a Solution?

We evaluated the effects of faking on mean scores and correlations with self-reported counterproductive behavior of integrity-related personality items administered in single-stimulus and forced-choice formats. In laboratory studies, we found that respondents instructed to respond as if applying for a job scored higher than when given standard or "straight-take" instructions. The size of the mean shift was nearly a full standard deviation for the single-stimulus integrity measure, but less than one third of a standard deviation for the same items presented in a forced-choice format. The correlation between the personality questionnaire administered in the single-stimulus condition and self-reported workplace delinquency was much lower in the job applicant condition than in the straight-take condition, whereas the same items administered in the forced-choice condition maintained their substantial correlations with workplace delinquency.
