Sentence-final word completion norms for European Portuguese children and adolescents

This study presents a set of sentence contexts and their cloze probabilities for European Portuguese children and adolescents. Seventy-three sentence contexts (35 low- and 38 high-constraint sentence stems) were presented to 90 children and 102 adolescents. Participants were asked to complete the sentence contexts with the first word that came to mind. For each sentence context, responses were listed and cloze probabilities of the words that were chosen to complete the sentence context were computed. Additionally, idiosyncratic and invalid responses (structural and semantic errors) were analyzed. A high degree of consistency in responses among the two age samples (children and adolescents) was found, along with a decrease of idiosyncratic and invalid responses in older participants. These results shed light on age-related changes in the effects of linguistic context on word production, and also in knowledge’s representation.

Perceptual and attentional factors in encoding irrelevant spatial information

Numerous studies found superior performance when the irrelevant location of a stimulus and response location were corresponding than when they were not corresponding (Simon effect), suggesting that stimulus location is processed in an obligatory manner. The present study compared Simon effects from the location of a relevant (i.e., to-be-attended) object to those from the location of an irrelevant (i.e., to-be-ignored) object. In four experiments, participants were presented with a rectangular frame and a square, with the relevant object in green or red color and the irrelevant object in gray or white color. Participants’ task was to respond with a lateral keypress to the color of the relevant object, and we varied spatial correspondence between the location of the relevant or the irrelevant object and the response, respectively. Results consistently showed larger Simon effects from the location of the relevant than from the irrelevant object, even when the irrelevant object was made very salient. These results suggest that location processing is largely confined to relevant (i.e., attended) objects, stressing the role of attention shifts for location encoding.     

Object-centred orienting of attention

Abstract

In the present study two experiments are reported in which the subjects were presented on a computer screen with a two-dimensional line drawing that is perceived as a three-dimensionalobject (i.e. a cube). The cube could be seen as stationary, as rotating about the y-axis (Experiment 1A), or as rotating about the x-axis (Experiment 1B). The subject's attention was directed by a visual precue to a vertex of the cube. As the cube rotated, the precued location moved in viewer-centred co-ordinatesm, but the local feature of the cube that had been precued (i.e. a given vertex) did not move in object-centred co-ordinates. The imperative stimulus was presented at the precued location (valid trials) or at an uncued location (invalid trials). Precued and uncued locations were determined in object-centred coordinates. The subjects were required to signal detection of the imperative stimulus by pressing the space bar on the computer keyboard. There were also control conditions in which the procedure was identical, but the cube was not visible. When the cube was visible, valid trials were faster than invalid trials, regardless of whether it was seen as stationary or rotating. It was concluded that the subjects could allocate spatial attention in object-centred co-ordinates. There wer also indications that responses for invalid trials were faster when the imperative stimulus was presented on the same face as the precue than when it was presented on the opposite face.     

Affective auditory stimuli: Adaptation of the International Affective Digitized Sounds (IADS-2) for European Portuguese

In this study, we present the normative values of the adaptation of the International Affective Digitized Sounds (IADS-2; Bradley & Lang, 2007a) for European Portuguese (EP). The IADS-2 is a standardized database of 167 naturally occurring sounds that is widely used in the study of emotions. The sounds were rated by 300 college students who were native speakers of EP, in the three affective dimensions of valence, arousal, and dominance, by using the Self-Assessment Manikin (SAM). The aims of this adaptation were threefold: (1)?to provide researchers with standardized and normatively rated affective sounds to be used with an EP population; (2)?to investigate sex and cultural differences in the ratings of affective dimensions of auditory stimuli between EP and the American (Bradley & Lang, 2007a) and Spanish (Fernández-Abascal et al., Psicothema 20:104–113 2008; Redondo, Fraga, Padrón, & Piñeiro, Behavior Research Methods 40:784–790 2008) standardizations; and (3)?to promote research on auditory affective processing in Portugal. Our results indicated that the IADS-2 is a valid and useful database of digitized sounds for the study of emotions in a Portuguese context, allowing for comparisons of its results with those of other international studies that have used the same database for stimulus selection. The normative values of the EP adaptation of the IADS-2 database can be downloaded along with the online version of this article.     

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.     

Psychometric properties of the Reynolds Child Depression Scale in community and clinical samples

The factor structure of the Reynolds Child Depression Scale (RCDS; Reynolds, 1989), analyzed by confirmatory factor analysis and the scale's psychometric characteristics in a sample of 315 participants (140 boys and 175 girls) and a clinical sample of 62 participants (37 boys and 25 girls) between 10 and 12 years old, are presented. Two models are tested with confirmatory factor analysis: a one-factor model and a five-factor model. Both models show a good fit, but the one-factor model was chosen because it is the most parsimonious. The reliability coefficient ranged from .87 (at test) to .89 (at retest) in the community sample, and was .90 in the clinical sample (at test). Test-retest reliability was .66 in the community sample. Concurrent validity with other self-reports that measure depressive symptomatology was high, both in the community sample (.76) and the clinical sample (.71). There were no significant sex differences but there were differences due to age (school grade).     

Grammatical category-specific deficits in bilingual aphasia

We report the naming performance of an early and highly proficient Spanish-Catalan bilingual (JPG) suffering from Primary Progressive Aphasia (PPA). JPG's performance revealed a grammatical category-specific deficit, with worse performance in naming verbs than nouns. This dissociation was present in oral and written naming and in his two languages, and it seems to stem from damage to, at least, the lexical level. Despite the fact that JPG's performance was qualitatively very similar across languages, his second language seemed to be more affected than his first language. These results indicate that the cortical organization of the two languages of highly proficient bilinguals follow similar organizational principles, one of this principles being grammatical class.     

Right—left prevalence effect with horizontal and vertical effectors

We investigated the right-left prevalence effect in spatial compatibility tasks by assessing subjects’ performance on a two-dimensional task in which both the horizontal and vertical spatial dimensions were task relevant. Two experiments were performed, in which stimulus-response mappings were one-dimensional (Experiment 1) and two-dimensional (Experiment 2). The subjects responded by using either horizontal or vertical effectors to stimuli appearing in four possible locations. With the one-dimensional mapping, the spatial compatibility effect was present only in the dimension relevant to the mapping. With the two-dimensional mapping, the horizontal compatibility effect was always present, whereas the vertical compatibility effect was present only when vertical effectors were used. This pattern of results indicates that horizontal coding takes place with either horizontal or vertical effectors, whereas vertical coding takes place only when vertical effectors are used.     

Engaging in upward and downward comparisons as a determinant of relative deprivation at work: A longitudinal study

A longitudinal study was conducted among 93 nurses to determine the role of comparing one’s performance with that of one’s colleagues in the increase versus decrease of perceived relative deprivation at work over a period of one year. Relative deprivation at T2 had increased particularly among those high in social comparison orientation (Gibbons & Buunk, 1999) who at T1 (1) more frequently engaged in upward comparisons; (2) more frequently derived positive as well as negative feelings from such comparisons; and (3) more frequently derived negative feelings from downward comparison. Moreover, engaging in downward comparison also led to an increase in perceived relative deprivation at T2. This study is one of the few to find evidence for longitudinal effects of social comparison activity, and the first to find that such effects occur only for those high in social comparison orientation.
