Logical Metonymy Resolution in a Words‐as‐Cues Framework: Evidence From Self‐Paced Reading and Probe Recognition

Logical metonymy resolution (begin a book → begin writing a book) has traditionally been explained either through complex lexical entries (qualia structures) or through the integration of the implicit event via post‐lexical access to world knowledge. We propose that recent work within the words‐as‐cues paradigm can provide a more dynamic model of logical metonymy, accounting for early and dynamic integration of complex event information depending on previous contextual cues (agent and patient). We first present a self‐paced reading experiment on German subordinate sentences, where metonymic sentences and their paraphrased version differ only in the presence or absence of the clause‐final target verb (Der Konditor begann die Glasur → Der Konditor begann, die Glasur spreading the icing). Longer reading times at the target verb position in a high‐typicality condition (baker + icing → spread ) suggest that we make use of knowledge activated by lexical cues to build expectations about events. The early and dynamic integration of event knowledge in metonymy interpretation is bolstered by further evidence from a second experiment using the probe recognition paradigm. Presenting covert events as probes following a high‐typicality or a low‐typicality metonymic sentence (Der Konditor begann die Glasur → SPREAD ), we obtain an analogous effect of typicality at 100 ms interstimulus interval.     

Sex differences in aversive memory in rats: Possible role of extinction and reactive emotional factors

Studies usually show better spatial learning in males and stronger emotional memory in females. Spatial memory differences could relate to diverse strategies, while dissimilar stress reactions could cause emotional memory differences. We compared male and female rats in two emotional (classical emotional conditioning and aversive discrimination memory) and two emotionally “neutral” tasks: (1) plus-maze discriminative avoidance, containing two open and two enclosed arms, one of which presenting aversive stimuli (light/noise). No differences were found in learning, retrieving, or basal emotional levels, while only male rats presented extinction of the task; (2) contextual fear conditioning – a cage was paired to mild foot shocks. Upon reexposure, freezing behavior was decreased in females; (3) spontaneous alternation – the animals were expected to alternate among the arms of a four-arm maze. No differences between genders were found and (4) open-field habituation was addressed in an arena which the rats were allowed to explore for 10 min. Habituation was similar between genders. Differences were found only in tasks with strong emotional contexts, where different fear responses and stress effects could be determinant. The lack of extinction of discriminative avoidance by females points out to stronger consolidation and/or impaired extinction of aversive memories.     

Memories of "Bad" Days Are More Biased Than Memories of "Good" Days: Past Saturdays Vary, but Past Mondays Are Always Blue

In a survey of 202 participants, Monday was cited most frequently as the worst morning (65%) and evening (35%); whereas Friday (43%) and Saturday (45%) were the best evening and morning, respectively. Test–retest reliability was higher for worst morning (.89) and evening (.83) judgments, compared to best morning (.44) and evening (.61) judgments. In a second survey of 353 participants, ratings of typical moods were lowest on Monday, rising to a peak on Saturday, but actual momentary moods showed little or no variation by day. Remembered moods from the previous Monday were more strongly related to typical moods than to actual moods, but the reverse was true of remembered moods from the previous Friday and Saturday.     

Psychometric Properties of an Italian Version of the Differentiation of Self Inventory-Revised (It-DSI-R)

The Differentiation of Self (DoS) is a key concept of Bowen’s theory, indicating a process that begins in early infancy and progresses throughout childhood and adolescence, to reach a basic level in early adulthood. This study examined the psychometric properties of an Italian version of the Differentiation of Self Inventory-Revised (DSI-R) Skowron, Schmitt, Journal of Marital and Family Therapy 29:209–222, 2003), a multidimensional measure assessing DoS as conceptualized by Bowen. The sample comprised 671 subjects (age 19–69 year). Exploratory and confirmatory factor analyses showed that the Italian DSI-R possesses good psychometric properties. Internal consistencies were adequate. Correlations with the Dyadic Adjustment Scale, the Symptom Checklist 90-Revised, and the trait form of the State-Trait Anxiety Inventory were consistent with the theoretical relations among the constructs. The findings confirm the use of DSI-R as a psychometrically sound measure of the differentiation of self in the Italian context. Implications for future research and clinical practice are addressed.     

Preflexes and internal models in biomimetic robot systems

The next generation of neuroprostheses, which are aimed at the restoration of natural movement of paralysed body parts or at the natural interaction with external devices, will be quite similar to biomimetic robot systems which attempt to duplicate the organization of the biological motor control system. In the paper, we review some of the organizing principles that have emerged in the last few years and might provide useful guidelines for a biomimetic design.
