Co-referential Processing of Pronouns and Repeated Names in Italian

In this study, we investigate whether co-referential processing across sentence boundaries is driven by universal properties of the general architecture of memory systems and whether cross-linguistic differences concerning the number of anaphoric forms available in a language’s referential inventory can impact the process of inter-sentential co-reference resolution. As a window into these questions, we test whether the repeated-name penalty (RNP) and the overt-pronoun penalty (OPP)—comprehension delays associated with repeated names and overt pronouns, respectively, in comparison to more reduced anaphoric forms in reference to salient antecedents—occur in Italian, examining the extent to which Italian resembles other null-subject languages, with focus on Spanish. Our self-paced reading experiment with factors Antecedent (Subject, Object) and Anaphor (Null Pronoun, Overt Pronoun, Repeated Name) found that Italian exhibits both an OPP and a (weaker) RNP, extending previous research that showed these effects in Spanish and strengthening the claim that co-reference resolution might be subject to universal principles.     

Gender differences on the Five to Fifteen questionnaire in a non‐referred sample with inattention and hyperactivity‐impulsivity and a clinic‐referred sample with hyperkinetic disorder

Lambek, R., Trillingsgaard, A., Kadesjö, B., Damm, D. & Thomsen, P. H. (2010). Gender differences on the Five to Fifteen questionnaire in a non‐referred sample with inattention and hyperactivity‐impulsivity and a clinic‐referred sample with hyperkinetic disorder. Scandinavian Journal of Psychology 51, 540–447. The aim of the present study was to examine gender differences in children with inattention, hyperactivity, and impulsivity on the Five to Fifteen (FTF) parent questionnaire. First, non‐referred girls (n = 43) and boys (n = 51) with problems of attention and hyperactivity‐impulsivity and then clinic‐referred girls (n = 35) and boys (n = 66) with hyperkinetic disorder (HKD) were compared on the FTF. Results suggested that non‐referred boys were more hyperactive‐impulsive than non‐referred girls, whereas clinic‐referred boys and girl with HKD were more similar than dissimilar on the FTF questionnaire. Secondly, it was examined whether the application of gender mixed norms versus gender specific norms would result in varying proportions of clinic‐referred children with HKD being identified as impaired on the subdomains of the FTF questionnaire. Based on results it was concluded that the use of a gender mixed normative sample may lead to overestimation of impairment in boys with HKD, but the type of sample applied to define impairment on the FTF should depend on the purpose for applying the questionnaire.     

Effect of low dose ionizing radiation exposure in utero on cognitive function in adolescence

Heiervang, K. S., Mednick, S., Sundet, K. & Rund, B. R. (2010). Effect of low dose ionizing radiation exposure in utero on cognitive function in adolescence. Scandinavian Journal of Psychology, 51, 210–215. Radiation from the Chernobyl nuclear power plant meltdown greatly affected several Norwegian counties. The cognitive consequences of in utero exposure to radiation from the Chernobyl accident have been intensely debated. This study examines the cognitive outcomes for those Norwegians who were exposed as fetuses to the fallout from Chernobyl. The participants, 84 adolescents who were exposed in utero to radiation from the most contaminated areas in Norway and 94 adolescents from areas not contaminated by the radiation, were tested on verbal and nonverbal IQ. Two data analyses were conducted. First, using a control‐group design, the IQ scores of exposed and unexposed adolescents were compared. Second, in a timing‐of‐exposure design, those exposed during the most sensitive period were contrasted with those exposed later in gestation. Adolescents exposed to low‐dose ionizing radiation in utero scored significantly lower in full‐scale IQ than unexposed adolescents. The difference was restricted to verbal IQ and was not evident for nonverbal IQ. The effect was not observed in exposed adolescents who had passed the most sensitive gestational period prior to the accident and thus were exposed to the radiation from Chernobyl exclusively after gestational week 16. These participants performed as well as the controls. Although the results should be interpreted cautiously due to the study’s nonrandomized design, the data add new and important support to the hypothesis that the Chernobyl accident may have had a subtle effect on the cognitive functioning of those exposed to low‐dose ionizing radiation in utero during the most sensitive gestational period.     

Telling losses: Personality correlates and functions of bereavement narratives

How and why do bereaved individuals talk about their loss? What are the personality correlates and social consequences of different kinds of bereavement narratives? Two studies were conducted to answer these questions. In Study 1, participants from online bereavement support groups and memorial websites wrote bereavement narratives. Participants high in Conscientiousness told brief, factual narratives; participants high in Neuroticism told self-focused contamination narratives; and participants high in Extraversion told narratives for social reasons. In Study 2, undergraduate participants responded to twelve narratives from Study 1. Participants felt more sympathetic concern but more social awkwardness and less acceptance towards contamination narrators compared to redemption narrators. The role of personality in the telling and reception of bereavement stories, and social support after loss, is discussed.     

Visual discrimination of vowel duration

Discrimination of vowel duration was explored with regard to discrimination threshold, error bias, and effects of modality and consonant context. A total of 122 normal-hearing participants were presented with disyllabic-like items such as /lal-lal/ or /mam-mam/ in which the lengths of the vowels were systematically varied and were asked to judge whether the first or second vowel was longer. Presentation was either visual, auditory, or audiovisual. Vowel duration differences varied in 24 steps: 12 with a longer first /a/ and 12 with a longer last /a/ (range: ±33–400 ms). Results: 50% JNDs were smaller than the lowest tested step size (33 ms); 75% JNDs were in the 33–66 ms range for all conditions but V /lal/, with a 75% JND at 66–100 ms. Errors were greatest for visual presentation and for /lal-lal/ tokens. There was an error bias towards reporting the first vowel as longer, and this was strongest for /mam-mam/ and when both vowels were short, possibly reflecting a sublinguistic processing strategy.     

Skilled speechreading: A single-case study

In a case study the cognitive characteristics of a skilled visual speechreader (SJ) was examined and compared to a control group. SJ is a 56 year old woman, skilled in visual speechreading. She differs from most of the 119 individuals in the control group, as she uses a particular speechreading strategy in which she attempts to repeat overtly each spoken word as soon as it has been uttered, and to summarize and fill in missing pieces of information whenever it is possible (e.g., during pauses) during the conversation.
SJ outperformed the control group on three types of tasks; a reading span task, performance in the asymptote level in the serial position curve, and verbal inference-making. SJ's results were discussed with respect to (a) how they relate to the general case (i.e., models based on group-data) and to (b) her speechreading strategy. From a clinical perspective it was suggested that it might be possible to practice the strategy as such, but any possible improvement is dependent on the individual's capability to process information in this way.     

Questions as Interventions: Perceptions of Socratic, Solution Focused, and Diagnostic Questioning Styles

A videotaped psychotherapy analogue compared psychology trainees' (n = 67) and undergraduate non-therapists' (n = 115) perceptions of three theoretically derived questioning styles: Socratic disputation in Rational Emotive Behavior Therapy (REBT), solution focused questioning (e.g. the miracle question), and diagnostic interviewing. Non-therapists rated REBT and diagnostic styles more highly than psychology trainees. All subjects rated solution focused questioning more highly than both other styles, perceiving it as more collaborative and conducive to the client's independent thinking. The constructs of collaborative empiricism and solution focused cooperation are discussed in relation to findings. The study also compared psychology trainees' and non-therapists' Big Five personality profiles, a topic which has not previously been addressed in the literature. Psychology trainees were higher in Big Five Openness and Agreeableness than non-therapists. Openness was negatively associated with ratings for solution focused and diagnostic questioning styles, replicating findings of previous analogue studies, in which undergraduate subjects preferred straightforward approaches to therapy.     

Chromatic rod vision VIII. Simultaneous contrast

Stabell, U. & Stabell, B. Chromatic rod vision. VIII. Simultaneous contrast. Scand. J. Psychol., 1973, 14, 1619.-Compared with the curve of additive opponent hue, the curve of scotopic hue of simultaneous contrast was found to be displaced toward blue in the orange and green-yellow regions of inducing field. The results are explained on the assumptions that (a) change of disposition for scotopic hue reflects variation in ratio of primary hue-related processes of inducing field, and (b) the chromatic-related opponent processes, in a dark-adapted and chromatically neutral eye, are of equal magnitude within the photochromatic interval.     

Comprehension and belief structure

Abstract.— A reader's belief structure is suggested to affect the way he processes incoming information. It is analyzed in terms of what propositions the reader regards as true (the truth values) and of how the reader discriminates between propositions as to truth value (the discrimination index). In a study on 20 psychology students, the comprehension task involved matching single statements to a previously read text. The statements represented two different ideas, whereas the text represented only one. The subjects' belief structure in terms of statements accepted (truth value) and statements discriminated as to truth value (discrimination index) was related to the way in which they matched the same Statements to the previously read text (comprehension). Truth values and discrimination indices together were found to account for 39% of the interindividual variation in comprehension after the first reading and for 50 % of that variation after the second reading. It is suggested that a reader, when confronted with a new text, arrives at the most probable interpretation of that text by turning to his own belief structure.     

Context-dependent latent inhibition in taste aversion learning

The effects of taste stimulus preexposure, either in the presence or in the absence of a specific contextual cue consisting of a specific noise-producing bottle, upon the conditioning and testing of conditioned taste aversions to the taste (saccharin) plus context (noisy-bottle) compound stimulus were investigated. Four groups of rats were given preexposure trials (latent inhibition) to either: (1) novel saccharin in novel noisy bottles, (2) novel saccharin in familiar silent bottles, (3) familiar water in novel noisy bottles, (4) familiar water in familiar silent bottles, in six trials. During conditioning, saccharin was presented in the noisy bottles followed by lithium chloride for all the groups. At testing, saccharin was presented in the noisy bottles for both one-bottle and two-bottle tests of aversion. It was indicated that the conditioning decrement produced after both saccharin and noisy bottle preexposure was overwhelmingly greater than any produced after preexposure to the elements. These results, discussed in relation to current theories of latent inhibition and perceptual learning, further underline the overwhelming significance of exteroceptive contextual elements in conditioned taste aversions.
