## jsPsych.data.addDataToLastTrial
|
||||
|
||||
```
|
||||
jsPsych.data.addDataToLastTrial(data)
|
||||
```
|
||||
|
||||
### Parameters
|
||||
|
||||
Parameter | Type | Description
|
||||
----------|------|------------
|
||||
data | object | Object of key: value pairs to add to the data from the last trial.
|
||||
|
||||
### Return value
|
||||
|
||||
Returns nothing.
|
||||
|
||||
### Description
|
||||
|
||||
This method appends data to the data recorded by the last trial. It's particularly useful when combined with the `on_finish` event handler for a trial, as shown in the example below.
|
||||
|
||||
|
||||
### Examples
|
||||
|
||||
#### Evaluate a response and add to data
|
||||
```javascript
|
||||
var block = {
|
||||
type: 'single-stim',
|
||||
stimuli: ['img/happy_face_1.jpg', 'img/sad_face_1.jpg'],
|
||||
choices: [89,78], // Y or N
|
||||
prompt: '<p class="center-content">Have you seen this face before? Y or N.</p>',
|
||||
on_finish: function(trial_data){
|
||||
// let's imagine that the correct answer is NO for both trials
|
||||
var correct = (trial_data.key_press == 78);
|
||||
jsPsych.data.addDataToLastTrial({correct: correct});
|
||||
}
|
||||
}
|

jsPsych.pluginAPI.getKeyboardResponse(parameters)

||||
### Parameters
|
||||
|
||||
The method accepts an object of parameter values (see example below). The valid keys for this object are listed in the table below.
|
||||
|
||||
Parameter | Type | Description
|
||||
----------|------|------------
|
||||
callback_function | function | The function to execute whenever a valid keyboard response is generated.
|
||||
valid_responses | array | An array of key codes or character strings representing valid responses. Responses not on the list will be ignored. An empty array indicates that all responses are acceptable.
|
||||
rt_method | string | Indicates which method of recording time to use. The `'date'` method uses calls to `(new Date()).getTime()` to record timing information. The `'performance'` method uses calls to `performance.now()`, which is a more modern JavaScript feature. The `'performance'` approach is [not supported by all the major browsers yet](http://caniuse.com/#search=performance), but adoption rates are increasing.
|
||||
rt_method | string | Indicates which method of recording time to use. The `'date'` method uses calls to `(new Date()).getTime()` to record timing information. The `'performance'` method uses calls to `performance.now()`, which is a more modern JavaScript feature. The `'performance'` approach is [not supported by all the major browsers yet](http://caniuse.com/#search=performance), but adoption rates are increasing. The `audio` method is used in conjuction with an `audio_context` (set as an additional parameter). This uses the clock time of the `audio_context` when audio stimuli are being played.
|
||||
audio_context | AudioContext object | The AudioContext of the audio file that is being played.
|
||||
audio_context_start_time | numeric | The scheduled time of the sound file in the AudioContext. This will be used as the start time.
|
||||
allow_held_key | boolean | If `true`, then responses will be registered from keys that are being held down. If `false`, then a held key can only register a response the first time that `getKeyboardResponse` is called for that key. For example, if a participant holds down the `A` key before the experiment starts, then the first time `getKeyboardResponse` is called, the `A` will register as a key press. However, any future calls to `getKeyboardResponse` will not register the `A` until the participant releases the key and presses it again.
|
||||
persist | boolean | If false, then the keyboard listener will only trigger the first time a valid key is pressed. If true, then it will trigger every time a valid key is pressed until it is explicitly cancelled by `jsPsych.pluginAPI.cancelKeyboardResponse` or `jsPsych.pluginAPI.cancelAllKeyboardResponses`.

### Parameters
|
||||
|
||||
Parameter | Type | Description
|
||||
----------|------|------------
|
||||
array | array | The array of values to shuffle
|
||||
equalityTest | function | A function to use to evaluate the equality of neighbors in the array. The function should accept two parameters, which are the two elements to be tested. It should return `true` if they are equal and `false` if not. The default function, if none is specified, is to use the `===` operator. This will work for primitive values, but fail for Objects and Arrays. An example function is given below in the examples.
|
||||
|
||||
### Return value
|
||||
|
||||
Returns an array with the same elements as the input array in a random order, with no repeating neighbors.
|
||||
|
||||
### Description
|
||||
|
||||
Shuffle an array, ensuring that neighboring elements in the array are different.
|
||||
|
||||
*Warning: if you provide an array that has very few valid permutations with no neighboring elements, then this method will fail and cause the browser to hang.*
|
||||
|
||||
### Examples
|
||||
|
||||
#### Basic example
|
||||
|
||||
```javascript
|
||||
|
||||
var myArray = [1,2,3,4,5,1,2,3,4,5,1,2,3,4,5];
|
||||
var shuffledArray = jsPsych.randomization.shuffleNoRepeats(myArray);
|
||||
|
||||
// output: shuffledArray = [2, 3, 5, 1, 2, 4, 1, 5, 4, 1, 3, 5, 4, 3, 2]
|
||||
```
|
||||
|
||||
#### Custom equalityTest
|
||||
|
||||
```javascript
|
||||
var myObjects = [
|
||||
{color:"blue"},
|
||||
{color:"red"},
|
||||
{color:"yellow"},
|
||||
{color:"orange"}
|
||||
];
|
||||
|
||||
var repeatedSet = jsPsych.randomization.repeat(myObjects,3);
|
||||
var shuffled = jsPsych.randomization.shuffleNoRepeats(repeatedSet, function(a,b) { return a.color === b.color });
|
||||
|
||||
// console.log(JSON.stringify(shuffled))
