Masked suffix priming and morpheme positional constraints

Although masked stem priming (e.g., dealer–DEAL) is one of the most established effects in visual word identification, it is less clear whether primes and targets sharing a suffix (e.g., kindness–WILDNESS) also yield facilitation. In a new take on this issue, we show that prime nonwords facilitate lexical decisions to target words ending with the same suffix (sheeter–TEACHER) compared to a condition where the critical suffix was substituted by another one (sheetal–TEACHER) or by an unrelated nonmorphological ending (sheetub– TEACHER). We also show that this effect is genuinely morphological, as no priming emerged in noncomplex items with the same orthographic characteristics (sportel–BROTHEL vs. sportic–BROTHEL vs. sportur–BROTHEL). In a further experiment, we took advantage of these results to assess whether suffixes are recognized in a position-specific fashion. Masked suffix priming did not emerge when the relative order of stems and suffixes was reversed in the prime nonwords—ersheet did not yield any time saving in the identification of teacher as compared to either alsheet or obsheet. We take these results to show that –er was not identified as a morpheme in ersheet, thus indicating that suffix identification is position specific. This conclusion is in line with data on interference effects in nonword rejection and strongly constrains theoretical proposals on how complex words are identified. In particular, because these findings were reported in a masked priming paradigm, they suggest that positional constraints operate early, most likely at a prelexical level of morpho-orthographic analysis.     

Drivers’ subtypes in a sample of Italian adolescents: Relationship between personality measures and driving behaviors

Considering a limited number of relevant personality measures (e.g., sensation seeking, impulsivity, locus of control, anxiety and altruism), the present study aimed to identify subtypes of drivers in an Italian sample of 207 adolescents aged 14–15 (52.7% girls) with heterogeneous moped riding experiences. Subtypes were compared on the basis of both self-report driving behaviors and two measures extracted from students’ performances on a moped simulator employing a specifically developed Rasch-based method. On the basis of cluster analysis, three subgroups were identified (profiles A, B, C). Profile B was characterized by high levels of sensation seeking and impulsivity, and low levels of altruism and anxiety. It showed high risk propensity considering both self-report and simulator measures. Profile A consisted of mostly females and was characterized by high levels of anxiety, externality and low levels of sensation seeking and altruism. While showing cautious driving behaviors, it did not differ from profile B in terms of crash involvement. Profile C was characterized by high levels of altruism and a more internal orientation; it showed the safest driving attitude.A relevant feature of this study is the direct assessment of driving behaviors by means of simulation performances, which nonetheless showed high concordance with self-report data. Congruence of our findings with previous studies on older and more experienced samples is discussed, along with the use of simulation, in the light of future perspective for research.     

The triadic legitimacy model: Understanding support to disobedient groups

In a social-psychological perspective, many scholars have argued that disobedience plays a significant role in avoiding the degeneration of the authority into autocracy and in promoting social change. In particular, the tripolar model (minority-majority-population) proposed by Mugny (1982) emphasized the role of the population for the stability or the progress of every society. Authority may indeed preserve the status quo only on the grounds of its influence on a large population. Likewise, protesters may achieve social change only by influencing and involving a large part of the population in their struggles. In understanding why people decide to join a protest, the aim of this article is to integrate Kelman and Hamilton's (1989) analysis of legitimacy with the tripolar model on social influence. The model we propose – namely the triadic legitimacy model (TLM) – explains the dialectic between social stability and social change by considering both authority's and disobedient groups' legitimacies.     

Corticospinal excitability during the observation of social behavior

Evidence suggests that the observation of an action induces in the observers an enhancement of motor evoked potentials (MEPs) recorded by the observer’s muscles corresponding to those involved in the observed action. Although this is a well-studied phenomenon, it remains still unclear how the viewer’s motor facilitation is influenced by the social content characterizing the observed scene. In the present study we investigated the facilitation of the corticospinal system during the observation of either an action that does not imply a social interaction (i.e., an actor throwing a ball against a wall), or an action which implies a social interaction (i.e., an actor passing a ball to a partner). Results indicate that MEPs amplitude is enhanced during the observation of a social rather than an individual action. We contend that the increase in MEPs activation might reflect an enhancement of the simulative activity stemming from the mirror system during the observation of social interactions. Altogether these findings show that the human corticospinal system is sensitive to social interactions and may support the role of the mirror neurons system in social cognition.     

Meaning is in the beholder’s eye: Morpho-semantic effects in masked priming

A substantial body of literature indicates that, at least at some level of processing, complex words are broken down into their morphemes solely on the basis of their orthographic form (e.g., Rastle, Davis, & New, Psychonomic Bulletin and Review 11:1090–1098, 2004). Recent evidence has shown that this process might not be obligatory, as indicated by the fact that morpho-orthographic effects were not found in a cross-case same–different task—that is, when lexical access was not necessarily required (Duñabeitia, Kinoshita, Carreiras, & Norris, Language and Cognitive Processes 26:509–529, 2011). In this study, we employed a task that required understanding a series of words and, thus, implied lexical access. Masked primes were shown very briefly right before the appearance of the target word; prime–target pairs entertained a morpho-semantic (dealer–DEAL), a morpho-orthographic (corner–CORN), or a purely orthographic (brothel–BROTH) relationship. Eye fixation times clearly indicated facilitation for transparent pairs, but not for opaque pairs (or for orthographic pairs, which were used as a baseline). Conversely, the usual morpho-orthographic pattern was found in a control experiment, employing a lexical decision task. These results indicate that the access to a morpho-orthographic level of representation is not always necessary for lexical identification, which challenges models of visual word identification that cannot account for task-induced effects.     

Discrimination of small quantities by fish (redtail splitfin, Xenotoca eiseni)

Discrimination of quantity has been argued to rely on two non-verbal representational systems: an object file system (OFS) for representing small values (≤3–4) and an analog magnitude system (AMS) for representing large magnitudes (>4). Infants’ ability to discriminate 1 versus 2, 1 versus 3, 2 versus 3, but not 1 versus 4 or 2 versus 4 seems to prove the independence of such systems. Here, we show that redtail splitfin fish (Xenotoca eiseni) performed relative quantity estimations preferring to approach the location previously occupied by the larger in number between two groups of conspecifics (no longer visible at test) in sets of 1 versus 2 and 2 versus 3 items, but failed at 3 versus 4 items, thus showing the same set-size limit as infants for discrimination of small quantities. However, when tested with quantities that spanned the boundary of the two systems, that is, 1 versus 4 and 2 versus 4, fish succeeded. These results thus point to either the use of continuous physical variables and/or the use of the AMS also for small numerousness in fish in this task.     

Self‐report measures,facial feedback,and personality differences (BEES) in cooperative vs. noncooperative situations: Contribution of the mimic system to the sense of empathy

The present study integrated three different measures of emotional empathic behavior in a social context: verbal self‐report measures (empathic response, emotional involvement, emotional significance, and valence), facial mimicry (activity of corrugator and zygomaticus muscles), and personal response to the Balanced Emotional Empathy Scale (BEES). Participants were presented with different interpersonal scene types (cooperation, noncooperation, conflict, indifference). Firstly, self‐rating on empathy, emotional involvement, and valence varied as a function of interpersonal context. Secondly, corrugator activity increased in response to conflictual and noncooperative situations; zygomatic activity increased in response to cooperative situations. Third, high‐ and low‐BEES subjects showed different empathic behavior: High‐empathic subjects were more responsive to empathy‐related situations than low‐empathic subjects. The convergence and divergence of these multidimensional measures was discussed.     

Do Mixed Unions Foster Integration? The Educational Outcomes of Mixed-Parentage Children in Italy

We investigate the nexus between intermarriage and immigrant integration by analyzing mixed-parentage children’s educational outcomes. We use Italian Labor Force Survey data to compare the upper secondary school participation of children of different types of mixed unions with that of children of two native and two migrant couples. Our results show that mixed-parentage children perform halfway between natives and immigrants, but their educational careers are highly heterogeneous. Among families with non-Western origins, mixed-parentage children improve substantially with respect to their peers with two migrant parents. But if the mother was born abroad, the children still exhibit higher dropout risks and lower general school enrolment as compared to children of natives and all other mixed-parentage children. A pivotal role in accounting for this educational disadvantage is played by the higher incidence in this specific type of union of nonstandard family dynamics and household fragilities that may give rise to less parental monitoring and lower educational performance. This finding is consistent with a prediction based on the status exchange theory, according to which such unions are more likely affected by instability and conflict.     

Lateral head turning affects temporal memory

Spatial attention is a key factor in the exploration and processing of the surrounding environment, and plays a role in linking magnitudes such as space, time, and numbers. The present work evaluates whether shifting the coordinates of spatial attention through rotational head movements may affect the ability to estimate the duration of different time intervals. A computer-based implicit timing task was employed, in which participants were asked to concentrate and report verbally on colour changes of sequential stimuli displayed on a computer screen; subsequently, they were required to reproduce the temporal duration (ranging between 5 and 80 sec.) of the perceived stimuli using the computer keyboard. There was statistically significant overestimation of the 80-sec. intervals exclusively on the rightward rotation head posture, whereas head posture did not affect timing performances on shorter intervals. These findings support the hypothesis that the coordinates of spatial attention influence the ability to process time, consistent with the existence of common cortical metrics of space and time in healthy humans.
