In a paired comparison participants were asked to rate how similar the two sounds sounded. The order of the stimuli was modified for each participant. Therefore, each `.html` indicates one listening test.</p>
Haptically perceived softness of deformable stimuli can be manipulated by applying external forces during the exploration
<p>The perception of softness is the result of the integration of information provided by multiple cutaneous and kinesthetic signals. The relative contributions of these signals to the combined percept of softness was not yet addressed directly. We transmitted subtle external vertical forces to the exploring human finger during the exploration of deformable silicone rubber stimuli to dissociate the force estimates provided by the kinesthetic signals and the efference copy from cutaneous force estimates. This manipulation introduced a conflict between the cutaneous and the kinesthetic/efference copy information on softness. We measured Points of Subjective Equality (PSE) of manipulated references to stimuli which were explored without external forces. PSEs shifted as a linear function of external force in predicted directions - to higher compliances with pushing and to lower compliances with pulling force. We found relative contribution of kinesthetic/efference copy information to perceived softness being 23% for rather hard and 29% for rather soft stimuli. Our results suggest that an integration of the kinesthetic/efference copy information and cutaneous information with constant weights underlies softness perception. The kinesthetic/efference copy information seems to be slightly more important for the perception of rather soft stimuli.</p> <p>Metzger, A., & Drewing, K. (2015).

Data from: Background matching can reduce responsiveness of jumping spiders to stimuli in motion
<p><span>Motion and camouflage were previously considered to be mutually exclusive, as sudden movements can be easily detected.</span> <span>Background matching, for instance, is a well-known, effective camouflage strategy where the color and pattern of a stationary animal match its surrounding background. However, background matching may lose its efficacy when the animal moves, as the boundaries of the animal become more defined against its background. Recent evidence shows otherwise, as camouflaged objects can be less detectable than uncamouflaged objects even while in motion.</span><span> Here, we explored if the detectability of computer-generated stimuli varies with the speed of motion, background (matching and unmatching) and size of stimuli in six species of jumping spiders </span><span>(Araneae: Salticidae)</span><span>. Our results showed that in general, the responsiveness of all six salticid species tested decreased with increasing stimulus speed regardless of whether the stimuli were conspicuousness or camouflaged. Importantly, salticid responses to camouflaged stimuli were significantly lower compared to conspicuous stimuli. There were significant differences in motion detectability across species when the stimuli were conspicuous, suggesting differences in visual acuity in closely related species of jumping spiders. Furthermore, small stimuli elicited significantly lower responses than large stimuli across species and speeds. </span><span>Our results thus suggest that background matching is effective even when stimuli are in motion, reducing the detectability of moving stimuli.</span></p>

Human Psychophysics Dataset on Figure Ground Segregation in Texture Stimuli
<div> <div>The dataset is derived from a psychophysics experiment where 8 participants discriminated the orientation of a rectangular figure within a texture stimulus comprised of Gabor annuli. The figure region differed from the background in its contrast distribution, controlled by two independent variables: Contrast Heterogeneity and Grid Coarseness. Contrast Heterogeneity refers to the range of contrasts exhibited by Gabor annuli. In this experiment, there were five values for Contrast Heterogeneity in the figure: 0.01, 0.2575, 0.505, 0.7525, and 1. The contrast distribution of the background was always maximally heterogeneous with Contrast Heterogeneity equal to 1. Grid Coarseness, on the other hand, refers to the scaling factor that controls the spacing between the Gabor annuli. It determines the density of the grid pattern in the background <em>and</em> the figure region. In this experiment, there were five values for Grid Coarseness: 1, 1.125, 1.250, 1.375, and 1.5. The experiment consisted of 9 sessions, each containing multiple blocks of trials. Each block of trials contained 25 unique stimulus conditions, defined by the combination of Contrast Heterogeneity and Grid Coarseness.</div> <div> <p><strong>Stimuli, Tasks, and Procedure </strong></p> </div> <div> <p>Each texture stimulus consisted of a full-screen irregular grid of non-overlapping Gabor annuli placed on a grey background. The Gabor annuli had a diameter of 0.7°, a spatial frequency of 5.7 cycles/degree, and a mean luminance of 60.76 Cd/m2. Embedded within this texture was a rectangular figure region located in the lower right quadrant of the screen, which differed from the rest of the texture in the contrast distribution of its annuli. For sessions 1-8, the figure center was placed at an eccentricity of (7 ± 1)° but slightly varied in terms of polar angle such that it was completely inside the lower right quadrant. For session 9 (transfer session), the figure was placed in the upper left quadrant. </p> </div> <div> <p>Participants were required to indicate whether the rectangular figure was oriented horizontally or vertically by pressing the right and left arrow keys, respectively. The experiment employed a two-alternative forced-choice design, in which participants had to make a decision about the orientation of the figure in each trial. Responses were given with the middle and index fingers of the right hand. In each trial, the stimulus was presented for 1000 ms or less if the participant lost fixation or provided a response. Participants were required to maintain fixation throughout the presentation of the stimulus. </p> </div> <div> <p>After each trial, participants received feedback on their response. If the response was correct, a green fixation point was presented for 500 ms. If the response was incorrect, a red fixation point was presented for 500 ms. </p> </div> <div> <p>The experiment was conducted in a dimly lit room. A chin and head-rest was used to support the participant's head and to keep eye-screen distance constant at 57 cm. Stimuli were displayed on a 19'' Samsung SyncMaster 940BF LCD monitor. Stimulus representation and response recording were performed using Psychtoolbox-3 for Matlab 64-Bit (Version 3.0.14 - Build date: Apr 6th, 2018) running on a Windows operating system. Fixation was monitored with a desktop-mounted Eyelink 1000 eye-tracker (SR Research Ltd.) with a sampling frequency of 500 Hz or 1000 Hz and a spatial resolution of <0.01° RMS. Eye-movement data were down-sampled to 250 Hz. </p> </div> <div> <p><strong>Procedure for Handling Aborted Trials </strong></p> </div> <div> <p>If a participant's gaze fell outside the fixation window during the fixation period preceding the stimulus, or during stimulus presentation, the trial was aborted. Aborted trials were repeated at a randomly chosen time during the experiment. </p> </div> <div> <p><strong>Parametrization of the Experimental Setup </strong></p> </div> <div> <p>The eye-screen distance was set to 57 cm. The stimulus presentation time was set to 1000 ms. The inter-trial interval was set to 900 ms. Each session consisted of 30 blocks, with 25 trials per block. </p> </div> <div> <p><strong>Transfer Session </strong></p> </div> <div> <p>The transfer session (session 9) was unique in that the rectangular figure was presented in the upper left quadrant of the screen, rather than the lower right quadrant as in sessions 1-8. This was done to test the transfer of learning to a new location. Participants were made aware of the figure displacement but were not told in which quadrant to expect it. </p> </div> <div> <p><strong>Variables </strong></p> </div> <div> <p>The dataset includes identifiers for each participant (SubjectID), session (SessionID), and block of trials (BlockID). For each trial, the dataset includes the condition (Condition), the contrast heterogeneity (ContrastHeterogeneity), the grid coarseness (GridCoarseness), the participant's response (IndicatedOrientation), the actual orientation of the rectangular region (ActualOrientation), and whether the participant's response was correct (Correct). The dataset also includes demographic information comprising their unique identifier (SubjectID), age (Age), and sex (Sex). </p> <p><strong>Ethics</strong></p> <p>After receiving full information about all procedures and about the right to withdraw participation at any time, they provided written informed consent according to the Helsinki Declaration. All procedures were approved by the local Ethical Committee of the Faculty of Psychology and Neuroscience (ERCPN). Participants received<br>monetary reward.</p> </div> </div>
Differences in dogs' event related potentials in response to human and dog vocal stimuli: A non-invasive study
<p>Recent advances in the field of canine neuro-cognition allow for the non-invasive research of brain mechanisms in family dogs. Considering the striking similarities between dog's and human (infant)'s socio-cognition at the behavioural level, both similarities and differences in neural background can be of particular relevance. The current study investigates brain responses of N=17 family dogs to human and conspecific emotional vocalisations using a fully non-invasive ERP paradigm. We found that similarly to humans, dogs show a differential ERP response depending on the species of the caller demonstrated by a more positive ERP response to human vocalisations compared to dog vocalisations in a time-window between 250-650 ms after stimulus onset. A later time-window between 800-900 ms also revealed a valence sensitive ERP response in interaction with the species of the caller. Our results are the first ERP evidence to show the species sensitivity of vocal neural processing in dogs along with indications of valence sensitive processes in later post-stimulus time-periods.</p>

<p>Electrophysiological recording of the membrane voltage (whole-cell patch-clamp) of three hippocampal CA1 pyramidal cells. Cells are stimulated with a current step chosen to ensure a firing rate around 5-10Hz (amplitude of the current step is given in the filenames) and a noise stimulus with zero mean (Ornstein-Uhlenbeck process with 4ms timescale). Each CSV file contains three columns, the timepoints (saved at 10000Hz), the noise stimulus, and the voltage trace recorded in response to the given noise stimulus. Voltages are recorded at low temperatures (around 32 degrees Celsius) and at high temperatures (around 37 degrees Celsius for cell 1, around 40 degrees Celsius for cells 2 and 3), exact temperatures are given in the filenames. The file metadata.csv contains additional information.</p>
Tadpoles rely on mechanosensory stimuli for communication when visual capabilities are poor
<p>The ways in which animals sense the world changes throughout development. For example, young of many species have limited visual capabilities, but still make social decisions, likely based on information gathered through other sensory modalities. Poison frog tadpoles display complex social behaviors that have been suggested to rely on vision despite a century of research indicating tadpoles have poorly-developed visual systems relative to adults. Alternatively, other sensory modalities, such as the lateral line system, are functional at hatching in frogs and may guide social decisions while other sensory systems mature. Here, we examined development of the mechanosensory lateral line and visual systems in tadpoles of the mimic poison frog (<em>Ranitomeya imitator)</em> that use vibrational begging displays to stimulate egg feeding from their mothers. <em>We found that tadpoles hatch with a fully developed lateral line system. While begging behavior increases with development, ablating the lateral line system inhibited begging in pre-metamorphic tadpoles, but not in metamorphic tadpoles.</em> We also found that the increase in begging and decrease in reliance on the lateral line co-occurs with increased retinal neural activity and gene expression associated with eye development. Using the neural tracer neurobiotin, we found that axonal innervations from the eye to the brain proliferate during metamorphosis, with little retinotectal connections in recently-hatched tadpoles. We then tested visual function in a phototaxis assay and found tadpoles prefer darker environments. The strength of this preference increased with developmental stage, but eyes were not required for this behavior, possibly indicating a role for the pineal gland. Together, these data suggest that tadpoles rely on different sensory modalities for social interactions across development and that the development of sensory systems in socially complex poison frog tadpoles is similar to that of other frog species.</p>
