Structural aspects of face recognition and the other-race effect

The other-race effect was examined in a series of experiments and simulations that looked at the relationships among observer ratings of typicality, familiarity, attractiveness, memorability, and the performance variables ofd’ and criterion. Experiment 1 replicated the other-race effect with our Caucasian and Japanese stimuli for both Caucasian and Asian observers. In Experiment 2, we collected ratings from Caucasian observers on the faces used in the recognition task. A Varimax-rotated principal components analysis on the rating and performance data for the Caucasian faces replicated Vokey and Read’s (1992) finding that typicality is composed of two orthogonal components, dissociable via their independent relationships to: (1) attractiveness and familiarity ratings and (2) memorahility ratings. For Japanese faces, however, we fond that typicality was related only to memorahility. Where performance measures were concerned, two additional principal components dominated by criterion and byd’ emerged for Caucasian faces. For the Japanese faces, however, the performance measures ofd’ and criterion merged into a single component that represented a second component of typicality, one orthogonal to thememorability-dominated component. A measure offace representation quality extracted from an autoassociative neural network trained with a majority of Caucasian faces and a minority of Japanese faces was incorporated into the principal components analysis. For both Caucasian and Japanese faces, the neural network measure related both to memorability ratings and to human accuracy measures. Combined, the human data and simulation results indicate that the memorahility component of typicality may be related to small, local, distinctive features, whereas the attractiveness/familiarity component may be more related to the global, shape-based properties of the face.     

The need for speed: Scores on a new video-based measure of speeding propensity,suitable for use in online research,correlate with drivers’ on-road speeding behaviour

A video-based measure of drivers’ speeding propensity (the UQ Video Speed Test) was developed for use in both laboratory-based and online research studies. In the test, the respondent is presented with a series of 16 video clips of traffic footage, which were shot from the driver’s perspective using a camera mounted behind the windscreen of a moving car. For each clip, the respondent’s task is to indicate to what extent they would travel faster or slower than the speed of the camera car. Responses to all clips are averaged to determine the respondent’s overall score. In the present study, we investigated associations between drivers’ video speed test scores and five measures of real everyday speeding behaviour obtained over a 5-week period using GPS trackers. There was a significant positive correlation for each of the five on-road speeding measures. In addition, age-related differences in test scores were consistent with observed real-world group differences in speeding behaviour. Test scores also correlated with an established self-report questionnaire measure of speeding (i.e., the Speed Scale from the Driving Style Questionnaire). Overall, the data supported the use of the UQ Video Speed Test as a proxy measure of drivers’ real-world speeding behaviour in laboratory-based and online studies (though it would be inadvisable to use such tests in the assessment of drivers for licensing purposes, due to the potential to “fake good”). The test can be deployed using standard online survey platforms (e.g., Qualtrics), and is available at no cost for use in driving research.     

Measuring Search for Meaning: A Factor-Analytic Evaluation of the Seeking of Noetic Goals Test (SONG)

This study’s primary purpose was to examine the factor structure of the 20-item Seeking of Noetic Goals (SONG) test via exploratory and confirmatory factor-analytic procedures. An additional objective was to report on the measure’s incremental validity in comparison to the Search scale of the Meaning in Life Questionnaire (MLQ), an alternative measure of search for meaning. This study utilized data from three samples of American undergraduates (N = 908) from a medium-sized southern university. Factor analysis supported a two-factor model of the SONG, with patterns of correlation further suggesting the measure assesses distinct constructs. Multi-group confirmatory factor analysis indicated similar scale structure and item answering in terms of gender. Overall, the first factor yielded reliable scores that correlated significantly and in the expected direction with measures of well-being and psychological distress. The second factor did not yield reliable scores nor did it correlate significantly with many of the other measures administered. However, both factors were shown to significantly predict scores from measures of depression and general psychological distress after controlling for MLQ Search scale scores. We consider the data with respect to SONG scoring and interpretation, and discuss implications of these data for future research.     

A Psychometric Evaluation of the Revised Parental Emotion Regulation Inventory

Despite significant research on parental emotion, parents’ regulation of their own emotions during discipline encounters is an understudied topic. Progress in this area of inquiry would be enhanced by the development of valid measures of emotion regulation. The present article describes an evaluation of such a measure, the revised Parental Emotion Regulation Inventory (PERI2). Mothers of 2-year-old children (N?=?232) completed the PERI2, additional questionnaire measures, and a parent-child observation during home visits. The present findings support the factorial and concurrent validity of the PERI2’s suppression (e.g., concealing negative emotion), capitulation (e.g., giving into aversive child behavior to reduce negative emotion) and escape (e.g., walking away mid discipline encounter to reduce negative emotion) factors. Suppression, capitulation, and escape were distinct but interrelated emotion regulatory behaviors that were associated with such factors as harsh parenting, lax discipline, parental maladjustment, and child physical aggression. In contrast, the psychometric adequacy of the reappraisal factor (e.g., thinking differently about the child’s behavior to reduce negative emotion) was not supported. The results support the future use of the PERI2, minus the reappraisal factor’s items.     

The reliability of eyetracking to assess attentional bias to threatening words in healthy individuals

Eyetracking is commonly used to investigate attentional bias. Although some studies have investigated the internal consistency of eyetracking, data are scarce on the test–retest reliability and agreement of eyetracking to investigate attentional bias. This study reports the test–retest reliability, measurement error, and internal consistency of 12 commonly used outcome measures thought to reflect the different components of attentional bias: overall attention, early attention, and late attention. Healthy participants completed a preferential-looking eyetracking task that involved the presentation of threatening (sensory words, general threat words, and affective words) and nonthreatening words. We used intraclass correlation coefficients (ICCs) to measure test–retest reliability (ICC > .70 indicates adequate reliability). The ICCs(2, 1) ranged from –.31 to .71. Reliability varied according to the outcome measure and threat word category. Sensory words had a lower mean ICC (.08) than either affective words (.32) or general threat words (.29). A longer exposure time was associated with higher test–retest reliability. All of the outcome measures, except second-run dwell time, demonstrated low measurement error (<6%). Most of the outcome measures reported high internal consistency (α > .93). Recommendations are discussed for improving the reliability of eyetracking tasks in future research.     

Semantic diversity: A measure of semantic ambiguity based on variability in the contextual usage of words

Semantic ambiguity is typically measured by summing the number of senses or dictionary definitions that a word has. Such measures are somewhat subjective and may not adequately capture the full extent of variation in word meaning, particularly for polysemous words that can be used in many different ways, with subtle shifts in meaning. Here, we describe an alternative, computationally derived measure of ambiguity based on the proposal that the meanings of words vary continuously as a function of their contexts. On this view, words that appear in a wide range of contexts on diverse topics are more variable in meaning than those that appear in a restricted set of similar contexts. To quantify this variation, we performed latent semantic analysis on a large text corpus to estimate the semantic similarities of different linguistic contexts. From these estimates, we calculated the degree to which the different contexts associated with a given word vary in their meanings. We term this quantity a word’s semantic diversity (SemD). We suggest that this approach provides an objective way of quantifying the subtle, context-dependent variations in word meaning that are often present in language. We demonstrate that SemD is correlated with other measures of ambiguity and contextual variability, as well as with frequency and imageability. We also show that SemD is a strong predictor of performance in semantic judgments in healthy individuals and in patients with semantic deficits, accounting for unique variance beyond that of other predictors. SemD values for over 30,000 English words are provided as supplementary materials.     

Exploring the relationship between children's knowledge of text message abbreviations and school literacy outcomes

This paper presents a study of 88 British 10–12‐year‐old children's knowledge of text message (SMS) abbreviations (‘textisms’) and how it relates to their school literacy attainment. As a measure of textism knowledge, the children were asked to compose text messages they might write if they were in each of a set of scenarios. Their text messages were coded for types of text abbreviations (textisms) used, and the ratio of textisms to total words was calculated to indicate density of textism use. The children also completed a short questionnaire about their mobile phone use. The ratio of textisms to total words used was positively associated with word reading, vocabulary, and phonological awareness measures. Moreover, the children's textism use predicted word reading ability after controlling for individual differences in age, short‐term memory, vocabulary, phonological awareness and how long they had owned a mobile phone. The nature of the contribution that textism knowledge makes to children's word reading attainment is discussed in terms of the notion of increased exposure to print, and Crystal's (2006a) notion of ludic language use.     

Test-expectancy and semantic-organization effects in recall and recognition

Two experiments examined whether people expecting recall are, compared with people expecting recognition, more likely to form associations between semantically related words in a list of to-be-remembered words. People were induced to expect either a recall or a recognition test on a critical list that included three conditions of semantic organization. Words in the unrelated (U) condition were semantically unrelated to all other words on the list, whereas words in the two related conditions were semantically related to one other list word. In the related-spaced (R-S) condition, the two related words appeared in input positions separated by 5-11 other items, whereas in the related-massed (R-M) condition, they appeared in adjacent input positions. Different groups received either an expected or unexpected recall (Experiment 1) or recognition (Experiment 2) test on the critical list. In both recall and recognition, (l) people expecting recall did better than those expecting recognition, (2) memory was worst for U words, next best for R-S words, and best for R-M words, and (3) the test-expectancy and semantic-organization effects were additive. A standardizedz-score measure of category dependency in memory indicated that (1) people expecting recall were not more likely than those expecting recognition to form interitem associations between the related words and (2) recognition was category dependent, but less so than recall. Within the framework of Anderson and Bower’s (1972, 1974) theory, these data indicate that, compared with people expecting recognition, those expecting recall are not more likely to form interitem associations by tagging more pathways connecting semantically related nodes but, rather, are more likely to tag the nodes themselves. The implications that semantic-organization effects in recognition have for the Anderson-Bower theory were also discussed.     

Lexical configuration and lexical engagement: When adults learn new words

People know thousands of words in their native language, and each of these words must be learned at some time in the person’s lifetime. A large number of these words will be learned when the person is an adult, reflecting the fact that the mental lexicon is continuously changing. We explore how new words get added to the mental lexicon, and provide empirical support for a theoretical distinction between what we call lexical configuration and lexical engagement. Lexical configuration is the set of factual knowledge associated with a word (e.g., the word’s sound, spelling, meaning, or syntactic role). Almost all previous research on word learning has focused on this aspect. However, it is also critical to understand the process by which a word becomes capable of lexical engagement—the ways in which a lexical entry dynamically interacts with other lexical entries, and with sublexical representations. For example, lexical entries compete with each other during word recognition (inhibition within the lexical level), and they also support the activation of their constituents (top-down lexical-phonemic facilitation, and lexically-based perceptual learning). We systematically vary the learning conditions for new words, and use separate measures of lexical configuration and engagement. Several surprising dissociations in behavior demonstrate the importance of the theoretical distinction between configuration and engagement.     

Scale of reading fluency in Spanish: measuring the components of fluency / Escala de fluidez lectora en español: midiendo los componentes de la fluidez

Abstract

The main purpose of this study was to design and validate a rating scale to measure reading fluency. As well as speed and accuracy, different dimensions of prosody were taken into account (volume, intonation, pauses and phrasing), aspects hardly considered in reading assessment. In addition, a measure of reading quality was included. 122 Spanish primary-school children (74 in Year 2 and 48 in Year 4) read aloud a narrative text. Using inter-rater criteria, children’s reading was assessed with this new rating scale (Scale of Reading Fluency in Spanish, SRFS) (Escala de Fluidez Lectora en Español, EFLE) and with the Multidimensional Fluency Scale (Rasinski, 2004). Standardized reading comprehension and prosodic reading tests were used as criterion measures. Results show acceptable reliability and validity coefficients. We conclude that SRFS appears to be a useful instrument for using in education and research contexts.     

Dates of entry and measures of imagery,concreteness, goodness,and familiarity for 1,046 words sampled from theOxford English Dictionary

TheOxford English Dictionary is the standard reference work for determining the earliest known instance of the occurrence of a word (its date of entry). Partly in order to facilitate research on the relation between the date of entry and other psychological variables, we gathered normative data on 1,046 words sampled from theOxford English Dictionary. We present data for scales that measure the imagery, concreteness, goodness, and familiarity values for words. These norms may also be of use to researchers who are not explicitly concerned with words’ date of entry, but who wish to sample words from a set that contains a large number of unfamiliar as well as familiar words.     

How language relates to belief,desire, and emotion understanding

Two experiments examined syntax and semantics as correlates of theory-of-mind (ToM). In Experiment 1 children’s language was examined at 3 years of age in relation to ToM at 3, 3.5, 4, and 5.5 years. Semantics predicted unique variance in later belief understanding but not desire understanding. Syntax did not explain unique variance in belief or desire. In Experiment 2 two measures of syntax and a measure of semantics were used with 65 3–5-year-olds. The syntax measures tested children’s understanding of word order and embedded clauses. They were related to false belief, but contrary to some predictions, were also related to emotion recognition. Performance on language control tasks with low syntactic demands correlated equally well with false belief. In both experiments performance on the syntax and semantics tasks was highly inter-correlated. We argue that ToM is related to general language ability rather than syntax or semantics per se.     

Media exposure and language experience: Examining associations from home observations in Mexican immigrant families in the US

The current exploratory study describes exposure to digital media in young children from Mexican immigrant homes and its association with language input and output. Using multiple recordings of children’s home environments, we report on the rate (i.e., percentage of total recording time), language (Spanish or English), and type (adult- or child-directed programming) of auditory media exposure in toddlers under three years of age (N = 30; M_age = 20;3 months). We also examine total adult words and adult-child conversational turns, as indicators of child language input, and the number of child language vocalizations as a measure of early language development. Findings showed that digital media comprised approximately 14 % of the child language environment that families selected to record, with wide variability observed. Children were more likely to be exposed to media in Spanish than English and adult-directed than child-directed programming. Children’s general media exposure was negatively associated with the amount of children’s vocalizations and conversational turns but not the quantity of adult words in the environment, suggesting that the relation between media exposure and child language development is likely not mediated by a general decrease in adult input in Mexican immigrant homes. Instead, media exposure may decrease opportunities for children to engage in conversation and practice language expression, both critical mechanisms for successful language acquisition. Selection of child-directed programming may encourage child vocalizations but is less likely to be in Spanish in these homes, which may reduce opportunities for engagement with Spanish-dominant adults. Together these findings provide a window into the nature of media exposure in children from Mexican immigrant homes and into the associations between media and language input and output. Directions for future research are discussed.     

Use of Objectification Theory to Examine the Effects of a Media Literacy Intervention on Women

Although the impact of the media’s thin ideal on body image may be lessened by media literacy, empirical support for this is inconsistent. Objectification theory, which suggests that certain social situations serve to increase women’s self-objectification (i.e., viewing self from a third person perspective), was used as a framework to understand this inconsistency. In particular, it was hypothesized that media literacy may involve both negative (heightened self-objectification) and positive (well-being) effects. We used both qualitative and quantitative measures, and two studies showed that viewing the video Slim Hopes increased state self-objectification, as well as self-esteem and positive affect. Implications for effective media literacy and self-objectification are discussed.     

Combined behavioural markers of cognitive biases are associated with anhedonia

Biases towards negative information, as well as away from positive information, are associated with psychopathology. Examining biases in multiple processes has been theorised to be more predictive than examining bias in any process alone. Anhedonia is a core symptom of psychopathology and predictive of future psychopathological symptoms. Finding that combined biases are associated with anhedonia would advance knowledge of the nature of emotional processing biases and the value of objective performance-based measures for identifying early risk markers. Participants (N?=?139) completed tasks that assess latency bias (dot probe) and biased recognition (two-alternative forced-choice) of emotional information, as well as an anhedonia measure. An index was computed for each task’s performance reflecting biased processing of positive and negative words. Only combined biases on both tasks were associated with anhedonia. Attentional bias was positively associated with anhedonia, but only when recognition bias for emotional words was high. Thus, assessing biases in multiple domains increased sensitivity to uncover relationships between emotional processing biases and anhedonic symptoms.     

Functional cerebral lateralization in subtypes of disabled readers

This study investigated the functional cortical organization of reading-disabled boys and age-matched normal readers. Subjects were initially classified according to E. Boder's (1971a. In B. Bateman (Ed.), Learning disorders. Seattle: Special Child Publications. Vol. 4.) distinction between dysphonetic children (who make nonphonetic, bizarre spelling errors), dyseidetic children (who make phonetically acceptable errors, but do not respond to some words as “wholes”), and children who display normal error patterns (who make phonetically acceptable errors and respond to words as “wholes”). It was hypothesized that different types of reading disability would be associated with different patterns of lateralized brain function. This proposal was examined by testing subjects on three experimental neuropsychological measures—hemispheric time-sharing, conjugate lateral eye movements, and tactile directional perception. Conjugate lateral eye movements were disregarded as the control subjects failed to show predicted asymmetries on this measure. The two other measures were considered valid and demonstrated atypical lateralization in the reading-disabled groups. Lateralization of verbal and/or spatial functiosn differed among the reading-disabled groups and an attempt was made to relate these atypical patterns to the type of reading difficulties presented.
