Overshadowed cues have reduced ability to retroactively interfere with other cues

The present series of experiments explores the interaction between retroactive interference and cue competition in human contingency learning. The results of two experiments show that a cue that has been exposed to a cue competition treatment (overshadowing) loses part of its ability to retroactively interfere with responding to a different cue that was paired with the same outcome. These results pose problems for associative models of contingency learning and are also difficult to explain in terms of current theories of causal reasoning. Additionally, it is proposed that in light of the interaction between interference and cue competition, interference could be used as an indirect measure for the study of cue competition effects.     

Assessing Attachment to Parents and Peers in Middle Childhood: Psychometric Studies of the Portuguese Version of the People in My Life Questionnaire

The People in My Life questionnaire (PIML) is one of the few available self-report measures for assessing children’s representations of the relationship with attachment figures (parents and peers) in middle childhood. The current study presents validation studies of the PIML in a sample of Portuguese children aged between 8 and 12 years (N?=?314) and adolescents aged between 13 and 18 years (N?=?281). The original factor structure, composed of a second-order factor of attachment and three first-order factors (Trust, Communication, and Alienation), was confirmed for both scales (Parents Attachment and Peers Attachment) in the sample of children and replicated in the sample of adolescents using confirmatory factor analyses. The Portuguese version of the PIML showed adequate internal consistency and correlated as expected with measures of intrapersonal and interpersonal functioning (internalizing and externalizing problems, prosocial behavior, quality of life, self-compassion, and emotion regulation strategies). The PIML proved to be a psychometrically robust measure of children’s representations of their relationships with parents and peers, representing an important advance in the measurement of attachment in middle childhood.     

The glass is not yet half empty: agitation but not <Emphasis Type="Italic">Varroa</Emphasis> treatment causes cognitive bias in honey bees

Honey bees (Apis mellifera) are prone to judge an ambiguous stimulus negatively if they had been agitated through shaking which simulates a predator attack. Such a cognitive bias has been suggested to reflect an internal emotional state analogous to humans who judge more pessimistically when they do not feel well. In order to test cognitive bias experimentally, an animal is conditioned to respond to two different stimuli, where one is punished while the other is rewarded. Subsequently a third, ambiguous stimulus is presented and it is measured whether the subject responds as if it expects a reward or a punishment. Generally, it is assumed that negative experiences lower future expectations, rendering the animals more pessimistic. Here we tested whether a most likely negatively experienced formic acid treatment against the parasitic mite Varroa destructor also affects future expectations of honey bees. We applied an olfactory learning paradigm (i.e., conditioned proboscis extension response) using two odorants and blends of these odorants as the ambiguous stimuli. Unlike agitating honey bees, exposure to formic acid did not significantly change the response to the ambiguous stimuli in comparison with untreated bees. Overall evidence suggests that the commonest treatment against one of the most harmful bee pests has no detrimental effects on cognitive bias in honey bees.     

The Minho Word Pool: Norms for imageability,concreteness, and subjective frequency for 3,800 Portuguese words

Words are widely used as stimuli in cognitive research. Because of their complexity, using words requires strict control of their objective (lexical and sublexical) and subjective properties. In this work, we present the Minho Word Pool (MWP), a dataset that provides normative values of imageability, concreteness, and subjective frequency for 3,800 (European) Portuguese words—three subjective measures that, in spite of being used extensively in research, have been scarce for Portuguese. Data were collected with 2,357 college students who were native speakers of European Portuguese. The participants rated 100 words drawn randomly from the full set for each of the three subjective indices, using a Web survey procedure (via a URL link). Analyses comparing the MWP ratings with those obtained for the same words from other national and international databases showed that the MWP norms are reliable and valid, thus providing researchers with a useful tool to support research in all neuroscientific areas using verbal stimuli. The MWP norms can be downloaded along with this article or from http://p-pal.di.uminho.pt/about/databases.     

A Measure of the Stability of Activities in a Family Environment

The Stability of Activities in the Family Environment (SAFE) measure was developed to assess aspects of the construct of family stability. An earlier version of the SAFE was revised to improve its psychometric properties and better elaborate the construct that underlies the measure. College students completed the revised SAFE and other measures of family functioning with respect to their families of origin and measures of current adjustment. Findings support the reliability, internal consistency, and factor structure of the SAFE. It is suggested that the results of the factor analyses and findings that different aspects of family stability demonstrated different patterns of relationships to indices of family functioning, are consistent with the presumption guiding the development of the SAFE that families achieve stability in diverse ways. The validity of the SAFE was further supported by its relationship to measures of current self-esteem and depression.     

On logic of complex algorithms

An algebraic approach to programs called recursive coroutines — due to Janicki [3] — is based on the idea to consider certain complex algorithms as algebraics models of those programs. Complex algorithms are generalizations of pushdown algorithms being algebraic models of recursive procedures (see Mazurkiewicz [4]). LCA — logic of complex algorithms — was formulated in [11]. It formalizes algorithmic properties of a class of deterministic programs called here complex recursive ones or interacting stacks-programs, for which complex algorithms constitute mathematical models. LCA is in a sense an extension of algorithmic logic as initiated by Salwicki [14] and of extended algorithmic logic EAL as formulated and examined by the present author in [8], [9], [10]. In LCA — similarly as in EAL-ω ⁺ -valued logic is applied as a tool to construct control systems (stacks) occurring in corresponding algorithms. The aim of this paper is to give a complete axiomatization. of LCA and to prove a completeness theorem. Logic of complex algorithms was presented at FCT'79 (International Symposium on Fundamentals of Computation Theory, Berlin 1979)

Tests of homogeneity of independent correlation coefficients

It is demonstrated that tests of homogeneity of independent correlation coefficients based on the simple forms of the normal andt approximations to the distribution of the correlation coefficients are comparable in terms of robustness, size and power.     

Personality types and behavioural activation and inhibition in adolescents

A hypothesis relating personality types to activity of the Behavioural Approach System (BAS) and the Behavioural Inhibition System (BIS) was tested in a sample of 1015 10–18-year-old adolescents. According to this hypothesis, Undercontrollers could be characterized as individuals with overactive BAS, Overcontrollers as individuals with overactive BIS, and Resilients as individuals with low activity of both systems. These predictions were generally confirmed. Psychometrically measured BAS and BIS appeared to be the strongest predictors of Undercontrolled and Overcontrolled prototypes, respectively. Resilients were characterized by low scores on both dimensions.     

Nine Months of Multicomponent Behavioral Treatment for ADHD and Effectiveness of MTA Fading Procedures

We examined 9-month data from the 14-month NIMH Multimodal Treatment Study of Children with ADHD (the MTA) as a further check on the relative effect of medication (MedMgt) and behavioral treatment (Beh) for attention-deficit/hyperactivity disorder (ADHD) while Beh was still being delivered at greater intensity than at 14-month endpoint, and conversely as a check on the efficacy of the MTA behavioral generalization/maintenance procedures. Intention-to-treat analysis at 9 months showed essentially the same results as at 14 months, after Beh had been completely faded; MedMgt and the combination (Comb) of medication and Beh were significantly superior to Beh and community care (CC) for ADHD and oppositional-defiant (ODD) symptoms, with mixed results for social skills and internalizing symptoms. All treatment-group differences examined as changes in slopes from 9 to 14 months were nonsignificant (we found general improvement for all groups). Slopes from baseline to 9 months correlated highly (r > .74, p < .0001) with slopes from baseline to 14 months for all groups. The time function from baseline to 14 months showed a significant linear, but not quadratic, trend for the main outcome measure (a composite of parent- and teacher-rated ADHD and ODD symptoms) for all groups. Findings suggest that in contrast to the hypothesized deterioration in the relative benefit of Beh between 9 and 14 months (after completion of fading), the MTA Beh generalization and maintenance procedures implemented through 9 months apparently yielded continuing improvement through 14 months, with preservation of the relative position of Beh compared to other treatment strategies.
