Strong reciprocity is real, but there is no evidence that uncoordinated costly punishment sustains cooperation in the wild

I argue in my target article that field evidence does not support the costly punishment hypothesis. Some commentators object to my reading of the evidence, while others agree that evidence in favour of costly punishment is scant. Most importantly, no rigorous measurement of cost-benefit ratios in the field has been attempted so far. This lack of evidence does not rule out costly punishment as a cause of human cooperation, but it does pre-empt some overconfident claims made in the past. Other commentators have interpreted my article as an anti-experimental pamphlet or as a flat denial of the existence of pro-social motives--which it was not intended to be. While we have enough data to establish the existence (and theoretical relevance) of strong reciprocity motives, I argue in this response that their efficacy (and policy relevance) has not been demonstrated.     

Differences in cortical activity related to motor planning between experienced guitarists and non-musicians during guitar playing

The influence of motor skill learning on movement-related brain activity was investigated using electroencephalography. Previous research has indicated that experienced performers display movement-related cortical potentials (MRCPs) of smaller amplitude and later onset compared to novices. Unfortunately, previous studies have lacked ecological validity with experimenters recording the MRCP prior to simple motor tasks and applying the results to more complex motor skills. This study replicated previous research using an ecologically valid motor skill; recording the MRCP from a group of experienced guitarists and a control group of non-musicians while they played a simple scale on the guitar. Results indicated no difference between groups in early motor planning. In contrast, the later, negative slope and motor potential components were of smaller amplitude and the negative slope began later in the experienced guitarists. The data may indicate that, for experienced guitarists, a reduced level of effort is required during the motor preparation phase of the task. These findings have implications for musical instrument learning as well as motor skill acquisition in general.     

Spatial cognition and crime: the study of mental models of spatial relations in crime analysis

Several studies employed different algorithms in order to investigate criminal's spatial behaviour and to identify mental models and cognitive strategies related to it. So far, a number of geographic profiling (GP) software have been implemented to analyse mobility and its relation to the way criminals are using spatial environment when committing a crime. Since crimes are usually perpetrated in the offender's high-awareness areas, those cognitive maps can be employed to create a map of the criminal's operating area to help investigators to circumscribe search areas. The aim of the present study was to verify accuracy of simple statistical analysis in predicting spatial mobility of a group of 30 non-criminal subjects. Results showed that statistics such as Mean Centre and Standard Distance were accurate in elaborating a GP for each subject according to the mobility area provided. Future analysis will be implemented using mobility information of criminal subjects and location-based software to verify whether there is a cognitive spatial strategy employed by them when planning and committing a crime.     

Anxiety and Depression in Patients with Amyotrophic Lateral Sclerosis and Their Caregivers

A large number of studies have investigated a variety of psychological aspects in people with Amyotrophic Lateral Sclerosis, but there is still considerable uncertainty concerning the actual morbidity, in particular for anxiety. We aim to evaluate depression levels and anxiety disposition in ALS patients and their caregivers, in comparison to healthy controls. We conducted a cross-sectional comparison between people with ALS, their caregivers and a non-clinical control group in order to evaluate anxiety and depression levels. 40 ALS patients, their caregivers and 40 healthy adult subjects completed the Beck Depression Inventory II (BDI-II) and the State-Trait Anxiety Inventory—Y2 scale (STAI). We compared overall and single item scores in order to find differences between the three groups. BDI-II scores were significantly different between groups. Depression scores were higher for patients than for healthy controls, in both somatic and psychological sub-scales. Caregivers presented higher levels of psychological depression in comparison with healthy controls, and lower scores of somatic depression in comparison to patients. No differences were found in trait anxiety levels comparing the three groups. ALS patients and their caregivers developed more depression related symptomatology than the non-clinical sample. However, susceptibility to anxiety for both patients and caregivers seemed to be at a normal level.     

Learning from text benefits from enactment

Classical studies on enactment have highlighted the beneficial effects of gestures performed in the encoding phase on memory for words and sentences, for both adults and children. In the present investigation, we focused on the role of enactment for learning from scientific texts among primary-school children. We assumed that enactment would favor the construction of a mental model of the text, and we verified the derived predictions that gestures at the time of encoding would result in greater numbers of correct recollections and discourse-based inferences at recall, as compared to no gestures (Exp. 1), and in a bias to confound paraphrases of the original text with the verbatim text in a recognition test (Exp. 2). The predictions were confirmed; hence, we argue in favor of a theoretical framework that accounts for the beneficial effects of enactment on memory for texts.     

Staring us in the face? An embodied theory of innate face preference

Human expertise in face perception grows over development, but even within minutes of birth, infants exhibit an extraordinary sensitivity to face‐like stimuli. The dominant theory accounts for innate face detection by proposing that the neonate brain contains an innate face detection device, dubbed ‘Conspec’. Newborn face preference has been promoted as some of the strongest evidence for innate knowledge, and forms a canonical stage for the modern form of the nature–nurture debate in psychology. Interpretation of newborn face preference results has concentrated on monocular stimulus properties, with little mention or focused investigation of potential binocular involvement. However, the question of whether and how newborns integrate the binocular visual streams bears directly on the generation of observable visual preferences. In this theoretical paper, we employ a synthetic approach utilizing robotic and computational models to draw together the threads of binocular integration and face preference in newborns, and demonstrate cases where the former may explain the latter. We suggest that a system‐level view considering the binocular embodiment of newborn vision may offer a mutually satisfying resolution to some long‐running arguments in the polarizing debate surrounding the existence and causal structure of newborns' ‘innate knowledge’ of faces.

Neat,Swine, Sheep,and Deer: Mill and Peirce on Natural Kinds

In the earliest phase of his logical investigations (1865–1870), Peirce adopts Mill's doctrine of real Kinds as discussed in the System of Logic and adapts it to the logical conceptions he was then developing. In Peirce's definition of natural class, a crucial role is played by the notion of information: a natural class is a class of which some non-analytical proposition is true. In Peirce's hands, Mill's distinction between connotative and non-connotative terms becomes a distinction between symbolic and informative and pseudo-symbolic and non-informative forms of representation. A symbol is for Peirce a representation which has information. Just as for Mill all names of Kind connote their being such, so for Peirce all symbols profess to correspond to a natural class.     

On the impact of words: interpretation,empathy and affect regulation

This paper offers a contribution towards furthering our understanding of a theme more usually associated with the Freudian tradition, namely the role and function of words as action, particularly in relation to the representational process and its somatic roots. Some reference to neuroscience research will be offered in this respect. It also considers the value of differentiating Empathy from Empathism, as defined by the Italian psychoanalyst Stefano Bolognini who distinguishes informing complementary countertransference from states of over‐concordance. Two analytic sessions taken from the intensive analysis of a deeply deprived late‐latency child showing violent behaviour are provided with the aim of illustrating the application of these concepts. It is argued that, given the same elaboration of the countertransference and the adequate empathic position on the part of the analyst, the difference in the outcome of the interpretation was made by the specific use of words—in this case the use or not of the personal pronoun―in the two sessions. As the case material is taken from the clinical work of a supervisee, some elements regarding the supervisory situation are also discussed in the paper.
